🎀 The Problem Given an integer array nums and an integer val, remove all occurrences of val in nums in-place. The order of the elements may be changed. Then return the number of elements in nums which are not equal to val. Consider the number of elements in nums which are not equal to val be k, to get accepted, you need to do the following things: Change the array nums such that the first k elements of nums contain the elements which are not equal to val. The remaining elements of nums are not important as well as the size of nums. Example: Input: nums = [3,2,2,3], val = 3 ,] class Solution { public int removeElement(int[] nums, int val) { int i, j; int k = 0; Arrays.sort(nums); for (i = 0; i < nums.length; i++) { if (nums[i] == val) {…  ( 4 min )

How I Fixed the Mystery of Corrupted File Downloads from AWS S3 When your users report "corrupted files" but everything looks fine on your end Last month, I ran into one of those bugs that makes you question everything you think you know about web development. Users were complaining that downloaded files from our document management system were "corrupted" and wouldn't open. The twist? The files were perfectly fine in our AWS S3 bucket. Picture this: You're building an application where users upload important kyc documents—driver's licenses, bank statements, tax documents. Everything seems to work perfectly during testing. Files upload fine, they're stored securely in S3, and when you download them through your admin panel, they open without issues. Then the support tickets start rolling…  ( 6 min )

These days, the hype around vibe coding feels limitless. Tools that promise to turn your ideas into apps with nothing more than a chat prompt are everywhere. But back in March this year, I came across a tweet from a developer who discovered that one of those tools, Lovable, was exposing a user's Supabase API key. While it was a publishable API key, it had no permissions or restrictions, and the developer was able to access all the app's data without authentication, just by looking at the public build. This is not innovation. This is a security breach waiting to happen. This is what happens when people lean too hard on the vibe. They build software by instinct, skip fundamentals, and trust that the tool knows best. But when you are shipping products that handle real data, real users, and r…  ( 6 min )

Accessible Angular Forms are essential to ensure that all our users – including those with disabilities – can interact with our Angular App effectively. By implementing forms with Accessibility (A11y) in mind, we meet legal (EAA 2025 ♿) and ethical standards, and create a more inclusive experience. Accessible forms work better with screen readers, keyboard navigation, and assistive technologies – which not only helps users with impairments but also enhances the overall UX of our Angular Apps. In Angular, we have two types of forms: Template-driven Forms: These are simpler and more declarative, relying on Angular Directives to create forms. They are built around the NgModel directive and generally used for simple forms. As the name suggests, these are implemented in the template through att…  ( 7 min )

Potential customers often arrive at your pricing page during the final stage of their journey. By this point, they’re likely already interested in your offering and are evaluating pricing models before making a purchase decision.  That’s why your pricing page layout plays a critical role in communicating your plans and guiding users toward the right plan for their needs. But what exactly makes a SaaS pricing page effective? Interestingly, most SaaS pricing pages tend to follow a similar structure. This isn’t by accident, which is explained by Jakob’s Law: Users prefer familiar experiences. When your pricing page resembles layouts they’ve seen before, it builds trust and reduces friction. Deviating too much from these expectations can actually hurt your chances of conversion. In this blog, …  ( 7 min )

In the past few years, AI has taken a front seat in how we work, build, and even learn. While that’s exciting in many ways, there’s something no one is really talking about — the quiet decline of true learning, especially in the programming world. As someone who's learning and building daily, I've noticed a shift that worries me. Here’s what’s going on. Let’s say AI takes over most software jobs. That fear alone is already discouraging a lot of beginners. They wonder: “Why should I learn to code if AI can already do it better and faster?” The result? Fewer people are even trying to learn. And among those who do, many quit early. Not because they’re lazy — but because the beginning is genuinely hard. Most people don’t realize that learning to code takes time, patience, and frustration.

Retrospectives generate valuable team insights, but those insights often get stuck in the tool where they were created. Your team discusses important improvements, identifies action items, and reaches consensus on priorities - then someone has to manually recreate everything in Confluence for documentation. Most teams face the same challenge: retrospective insights need to live in Confluence for stakeholder updates, team reference, and organizational knowledge - but manual recreation is time-consuming and details get lost. Kollabe's new Confluence integration transforms completed retrospectives into comprehensive Confluence pages with a single click. Complete retrospective summary: All items, discussions, and outcomes Professional formatting: Clean, readable layouts that preserve context Action items highlighted: Key takeaways prominently displayed Voting data preserved: Team consensus and priority rankings maintained Choose exactly where your documentation goes: Select specific Confluence space Pick exact page hierarchy location Integrate with existing documentation structure Maintain organizational consistency Retrospective insights become permanent, searchable team knowledge instead of isolated session records. Teams can: Reference past improvements when similar issues arise Track improvement themes across multiple sprints Share outcomes with stakeholders easily Build organizational memory that survives team changes The setup is straightforward: Connect your Confluence account via OAuth Select your target space and page location Click export after your retrospective Access formatted documentation immediately This feature is available for all Kollabe users. Turn your retrospective insights into lasting team documentation that stakeholders can access and teams can reference for continuous improvement.

Introduction This article is a continuation of Expose home server with Rathole tunnel and Traefik article, which explains how to permanently host websites from home by bypassing CGNAT. That setup works well for exposing a single home server (like a Raspberry Pi, server PC, or virtual machine), but it has a limitation: it requires one VPS (or at least one public network interface) per home server. This is because the Rathole server exclusively uses ports 80 and 443. But it doesn't have to be like this. We can reuse a single Rathole server for many tunnels and home servers, we just need a tool to load balance their traffic, as long as our VPS's network interface provides enough bandwidth for our websites and services. This article explains how to achieve that using Traefik HTTP and TCP rou…  ( 8 min )

Why Encoding? tokenization. In Natural Language Processing (NLP), we use TensorFlow's Keras API **to easily convert text into sequences of numbers using a **Tokenizer. Why use tensorflow.keras? For smoother experience, especially when using TensorFlow, tools like Google Colab are recommended to avoid installation issues. 1. Tokenisation Explanation: tok=tokenizer() it is an initialisation of tokeniser which will break sentence into words. corp, corpus or paragraph which we will break it. tok.fit_on_texts(corp), it will give index to words. How indexing works in here? the most frequent word get lowest index like 1. print(tok.word_index), it ask for what is word index. 2. Convert text to sequences Problem: What Happens with New Words? When you train a tokenizer on some text, it only builds a vocabulary from those words. Example Without OOV Handling we tokenised the text into word and it have assigned the index. Now try a sentence with a new word "black": Now we have add word black texts_to_sequences() skip the word black. Handle OOV (Out-of-Vocabulary) Words Out of vocabulary words is word that is not present during training fit_on_texts(). Output: {'balck': 1, 'i': 2, 'need': 3, 'coffe': 4, 'we': 5, 'can': 6, 'make': 7, 'it': 8, 'from': 9, 'water': 10} Even though "black" wasn’t in training, it gets index 1 — the reserved OOV token. Limiting the number of words. Let say I don't want whole paragraph I want to limit the words why? because of efficiency if I take corpora (whole paragraph) then to process it will take time. To make it easy we will limit it. tok=Tokenizer(oov_token='balck',num_word=4)  ( 4 min )

I’ve been exploring an idea for a fully automated AI-powered cryptocurrency trading system that could be built entirely using free and publicly available services. The concept combines Groq AI for ultra-fast decision-making, a free crypto news API to analyze real-time market sentiment, and exchange APIs like Binance’s to execute live trades and monitor balances. The system would automatically analyze trends, interpret news, and make informed trading decisions in real time. It would also include a web-based dashboard to display capital status, trade logs, AI insights, and profit and loss — all updated live for full transparency. The goal is to create a highly efficient, intelligent, and low-cost crypto trading setup using freely accessible tools and APIs. It’s still just an idea at this stage, but I believe it has strong potential.

What is a coroutine object? A coroutine is a special kind of function that can pause and resume its execution, allowing asynchronous programming. When you call an async function, it doesn’t run immediately like a regular function. Instead, it returns a coroutine object — essentially a “promise” that it will run when awaited. async def say_hello(): print("Hello!") return "Done" result = say_hello() # This returns a coroutine object, it does NOT execute yet print(result) # # To actually run the coroutine and get the result, you need to await it: output = await say_hello() # Now it runs, prints "Hello!" and returns "Done" print(output) # "Done" Coroutine objects represent tasks that haven’t run yet. You must await them inside an async function to actually execute the code and get the result. If you don’t await and just return the coroutine, it’s like returning a “recipe” instead of the “finished dish.” Your repository functions are async (return coroutine objects). If you return the coroutine itself (without await), FastAPI tries to serialize the coroutine object, which causes errors. You must await those async calls so FastAPI gets the actual data to send in the response.

Overview, Historical Timeline, Problems & Solutions In Python, all data is made of objects. A number is an object. A string is an object. A list is an object. Even functions and classes are objects. Python treats everything as an object so it can store, copy, or link all parts of a program. When you run a program, you give Python values. Python turns those values into objects. The object holds data and also knows what it can do. This is what makes Python flexible and powerful. Python lets you represent all data as objects. name = "Ada" age = 36 Each value here becomes an object. The word name points to a string object. The word age points to a number object. Every object in Python has three parts: identity, type, and value. The identity is like a tag number. It never changes. The type …  ( 7 min )

INSERT INTO customers (name, email) VALUES ('Jane', 'jane@example.com'); Insert multiple rows: INSERT INTO customers (name, email) VALUES ('Jane', 'jane@example.com'), ('Mark', 'mark@example.com'); Batch Your Inserts Group records into one INSERT statement. Use Transactions Reduce overhead by committing only once: BEGIN; INSERT INTO ...; COMMIT; Delay Commits Especially for 1000+ row inserts. Bulk Tools Use LOAD DATA INFILE (MySQL) or other tools for large imports. Default Values Set up default values in your schema to simplify inserts. Insert from Another Table INSERT INTO archive_table SELECT * FROM main_table WHERE status = 'closed'; Auto-fill Fields with DEFAULT CREATE TABLE example ( id SERIAL, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ); Lock Tables for Heavy Inserts Prevents other queries from interfering. DbVisualizer: A great SQL client with visual tools for editing, running, and debugging INSERT queries. SQL Loader Tools: Try native bulk import tools if you're moving big datasets. Yes—list only the columns you're inserting. LOAD DATA safe for production? Yes, if you're careful about file format and permissions. INSERT with data from other tables? Yes! Combine it with SELECT for mass transfers. If you're not optimizing your INSERT queries, you're leaving performance on the table. Use the techniques here to reduce load times, save resources, and write cleaner code. Read the article INSERT INTO SQL Clause for more details.  ( 17 min )

Kubernetes is a powerful system—but with great power comes great responsibility. As clusters grow and more users or services interact with them, access control becomes a critical aspect of your security posture. This is where RBAC (Role-Based Access Control) comes into play. In this article, we’ll demystify Kubernetes RBAC, explain how it works, and walk through practical examples to help you implement it effectively. What Is RBAC in Kubernetes? Grant read-only, read-write, or admin access to specific resources. Limit users or services to namespaces or cluster-wide resources. Enforce the principle of least privilege. RBAC Key Components Role:-Defines a set of permissions within a namespace. ClusterRole: Like Role, but applicable cluster-wide. RoleBinding: Grants a Role to a user/service ac…  ( 4 min )

There’s something strangely poetic about failing 147 times in a row… and still pressing “retry.” That’s Flappy Bird for you — a game that feels like an inside joke between coders and chaos. But instead of just flapping endlessly and rage-quitting like most of us did in 2013, I decided to take a different route: analyze the game using Python. Because sometimes, understanding the monster is the only way to tame it. Why Flappy Bird Still Holds Our Attention As a Python dev, I couldn’t help but think: What if we could quantify the chaos? What if we could understand the rhythm of those pipes, the bird’s flight physics, or the hitbox sensitivity — all through code? Using Python to Analyze Gameplay Data Success rate per session And let me tell you — once I plotted my own “death heatmap,” I realiz…  ( 5 min )

Tired of 403s and blank pages when scraping JavaScript-heavy websites? Looking for one library which can take care of 403, js rendering automatically? You're not alone — and that's exactly why I built ScrapeSome. ScrapeSome is a developer-friendly Python library that makes scraping modern websites simple — even the ones loaded with dynamic JavaScript or tough anti-bot protections. It’s fast, lightweight, and requires zero boilerplate. I kept hitting walls on scraping projects: Pages rendered everything with JavaScript APIs were locked down or undocumented requests/Scrapy failed or got 403 error Setting up full browser automation felt too heavy for small jobs So I built ScrapeSome — to fill the gap between requests and full-on headless scraping frameworks. Handles both static and JS-heavy …  ( 5 min )

When I started learning the Java basics. One of the first things I came across was data types. it’s very important. Let me share what I understood so far. Data Types: Java has two main types of data types: Primitive Data Types. In this post I will give the outline Primitive Data Types. There are 8 Primitive Data Types: byte | 1 byte | Small whole numbers | byte a = 10; | short | 2 bytes | Bit bigger numbers | short b = 1000; | int | 4 bytes | Most common whole numbers | int age = 25; | long | 8 bytes | Huge whole numbers | long stars = 123456789L; | float | 4 bytes | Decimal numbers | float price = 12.5f; | double | 8 bytes | More accurate decimals | double pi = 3.14159; | char | 2 bytes | Single character | char letter = 'A'; | boolean | 1 bit | True or False | boolean isJavaFun = true; | My Personal Suggesion: First start with int for numbers and double for decimals.  ( 3 min )

How to Speak Up and Get Promoted in an IT Company While every company operates differently, the overall mechanics of career growth and salary increases in the IT industry tend to follow similar patterns. At some point, almost every professional — from junior developers to seasoned tech leads — faces the same question: How do I speak up and get recognized if I want to grow or earn more? To move forward successfully, it's important to understand not only your personal goals but also the company's motivations. When a company opens a new position, the primary goal is usually the same: improve business efficiency and profitability. Common reasons include: Filling a specific team role. Increasing team productivity and delivery speed. Reducing pressure on key individuals. Improving product q…  ( 5 min )

When you install or run Python-based tools on Arch Linux — especially from the AUR — you might notice that your system accumulates a lot of __pycache__ directories. These are generated when Python byte-compiles modules, but they aren’t always removed when you uninstall a package. In this short guide, we’ll walk through how to identify and optionally clean up those __pycache__ directories — specifically the ones not owned by any package — and exclude system paths like Flatpak while we're at it. Tools installed via the AUR (like waydroid-scripts-git, for example) might drop files under /opt, /usr/local, or other places. These files (especially .py and __pycache__) might not be tracked by pacman, so even after uninstalling the tool, leftover Python cache directories can remain. __pycache__ Directories Here’s a one-liner that will: Search your system for all __pycache__ directories Skip the Flatpak directory (/var/lib/flatpak) Check whether each is owned by any package Print only the ones that are not owned find / -type d -name '__pycache__' -not -path '/var/lib/flatpak/*' 2>/dev/null | while read dir; do pacman -Qo "$dir" &>/dev/null || echo "Not owned: $dir" done Not owned: /opt/waydroid-scripts/tools/__pycache__ Not owned: /usr/local/lib/python3.11/site-packages/some_tool/__pycache__ __pycache__ directories aren't dangerous, but they can accumulate and clutter your system — especially in directories that aren’t cleaned by package managers. With a few commands, you can find and clean up these leftovers safely, keeping your system neat and under control. Have your own cleanup tricks? Share them in the comments!  ( 3 min )

Introduction Force-pushing in Git (git push --force) is a powerful but dangerous command. It overwrites remote changes without checking if others have pushed new commits, which can lead to lost work. Fortunately, Git provides a safer alternative: git push --force-with-lease. This command ensures you don't accidentally overwrite someone else's changes while still allowing you to rewrite history when needed. In this guide, we'll explore how --force-with-lease works, when to use it, and best practices for avoiding mistakes. --force-with-lease Works Unlike --force, which blindly overwrites the remote branch, --force-with-lease checks if the remote branch has changed since you last fetched it. git push --force → Overwrites remote branch no matter what. git push --force-with-lease → Only o…  ( 6 min )

One of the most powerful features of cloud computing is scalability—and Microsoft Azure makes it incredibly simple with Autoscaling. Whether you're hosting a small web app or a full-scale enterprise platform, you don’t want to be manually adjusting resources every time traffic spikes. That’s where Azure’s autoscaling steps in. Autoscaling means your application can automatically increase or decrease resources based on demand. Instead of overprovisioning (and overpaying) or dealing with performance issues during traffic spikes, you set rules that let Azure do the scaling for you. Azure supports autoscaling for several services: App Services Virtual Machine Scale Sets Azure Kubernetes Service (AKS) Azure Functions In this guide, we’ll focus on App Service autoscaling, since it’s one o…  ( 4 min )

JavaScript’s type coercion and dynamic typing system are full of subtle (and sometimes surprising) behaviors. Understanding these quirks can make you much more confident and effective as a JS developer. Here’s a list of not-so-obvious JavaScript type coercion examples, grouped into categories with explanations: 1. String vs Number Comparison Expression Value Reason '10' < '2' true Lexicographic comparison: '1' comes before '2' '10' < 2 false string '10' is coerced to number 10 '5' == 5 true string '5' is coerced to number 5 '5' === 5 false strict equality, no type coercion Rule: Loose equality (==) allows type coercion. Strict equality (===) does not. 2. Falsy Values JavaScript has falsy values that act like false i…  ( 4 min )

Smart contracts are the backbone of decentralized applications (dApps) on the Ethereum blockchain. These contracts are written in Solidity, a statically typed, contract-oriented programming language tailored for Ethereum. One critical yet often overlooked aspect of smart contract development is how contracts are initialized when deployed to the blockchain. This blog post offers a deep dive into the concept of constructors in Solidity, how they work, their purpose, and best practices to keep your contracts secure and efficient. A constructor is a special function in a Solidity contract that is executed only once, at the moment the contract is deployed. Think of it as the setup phase of your smart contract—this is where you define the initial state, set permissions, or configure parameters t…  ( 5 min )

It’s Always the Refund It started, as these things always do, with a Slack message from support that began: "This is probably nothing, but…" It never is. Turns out a customer had requested a refund for a $0 order—paid entirely with a promotional code that someone in marketing named “YOLO100.” Our system, ever obedient, generated a pristine digital refund for exactly zero currency units and confidently shoved it into the payment gateway, which replied with the transactional equivalent of a raised eyebrow: "Invalid amount." From there, the trail of confusion expanded outward like a suburban sprawl. Engineering said it shouldn’t be possible. QA said it wasn’t in the test cases. Product said it was “an edge case.” (They always say that, don’t they? Every single cliff we fall off was once c…  ( 6 min )

Why RWAs aren’t the decentralized revolution you think they are Tokenized real-world assets (RWAs) are the new crypto darling. Everyone’s hyped: BlackRock’s onchain, treasuries are getting wrapped, and traditional finance is flirting hard with blockchain. But let’s not get it twisted: RWAs aren’t decentralization. They’re TradFi in a blockchain costume. Here’s the inconvenient truth: Want to buy tokenized real estate? Great. But that token doesn’t give you squat unless a legal entity off-chain honors it. Treasury tokens? Same thing. You’re trusting a fund manager, custodian, or regulatory body to redeem it. It’s not trustless. It’s regulatory theater with a smart contract backend. RWAs are less about empowering users and more about navigating global compliance. It’s not about breaking the system. It’s about bending the rules just enough to extract value while pretending to be futuristic. This isn’t DeFi. It’s just TradFi with faster accounting. Let’s be honest: most RWA projects don’t need a blockchain. They use it for: Token issuance Cap table management Tracking asset flow But these are things spreadsheets and CRMs have done for decades. Putting it onchain doesn’t make it revolutionary — it just makes it buzzword-compliant. Web3 wasn’t about rehypothecating bonds or making banks more efficient. It was about disintermediation. Cutting out the middlemen. Giving power back to users. Trustless systems. RWAs? They reintroduce the middlemen — they just wear hoodies now. Tokenized RWAs sound sexy, but they’re just Wall Street playing dress-up in Web3. Until these assets are truly decentralized — not just onchain — they’ll remain more TradFi than DeFi.  ( 3 min )

Instructions: Create a function finalGrade, which calculates the final grade of a student depending on two parameters: a grade for the exam and a number of completed projects. This function should take two arguments: exam - grade for exam (from 0 to 100); projects - number of completed projects (from 0 and above); This function should return a number (final grade). There are four types of final grades: 100, if a grade for the exam is more than 90 or if a number of completed projects more than 10. Examples(Inputs-->Output): 85, 5 --> 90 55, 3 --> 75 55, 0 --> 0 Thoughts: 1.I use the if/else statement to determine the return of the final grade function of different conditions.

Primeiro, vamos com calma Antes de tudo, vamos com calma. Sei que esse tipo de afirmação pode gerar problemas de entendimento e até certo favoritismo em relação a tecnologias. Entretanto, precisamos ter em mente as necessidades que nossas ferramentas suprem e por que devemos usá-las. Nos primórdios do desenvolvimento web, quando queríamos conectar e criar ferramentas, não existiam conceitos como micro-frontends, SaaS, microservices ou nada parecido. O mais próximo disso eram aplicações monolíticas, desenvolvidas com stacks que seguiam arquiteturas “quadradas” e bem estabelecidas. Um exemplo clássico é a infame stack LAMP: Linux Apache MySQL PHP Nessa época, era comum seguir a arquitetura MVC (Model-View-Controller), onde: A View apresentava os dados e recebia as entradas dos usuários; O …  ( 5 min )

Preventing direct administrative SSH access is a vital component of any defense-in-depth strategy. In this guide, we’ll explore how to restrict privileged users from logging in via SSH using SELinux’s ssh_sysadm_login boolean. This ensures that administrative access is only available after connecting through a restricted, non-privileged jump account — a critical safeguard against misconfiguration and privilege abuse. Overview: Why Restrict Admin SSH Access Step 1: Ensure SELinux is in Enforcing Mode Step 2: Associate Admin Users with sysadm_u Step 3: Disable ssh_sysadm_login Why Not Just Use sshd_config Final Thoughts & Additional Hardening Tips In Part 1 of this series, we set up a restricted jump user — a non-privileged account used to SSH into a Linux server.

AI-Powered Code Generation From Design Streamlining Design-to-Code Conversion AI tools are really changing how we build things, especially when it comes to turning design mockups into actual working code. It used to be that developers would spend a ton of time just translating what a designer made into code. Now, AI can take those designs and spit out production-ready code in a fraction of the time. This means projects can move a lot faster, and teams aren't stuck in that slow back-and-forth process. It's like having a super-fast assistant that understands design and can write code. This shift lets developers focus on more complex problems instead of repetitive coding tasks. It's a big deal for getting products out the door quicker. The whole idea is to cut down on the manual work involved…  ( 7 min )

What is Binary Search Imagine you are playing a game where you try to guess a secret number from 1 to 10, and you have infinite attempts. You can choose random numbers (without repetition)—maybe you will get lucky and guess it on the first try, or it might take you all 10 tries to reach it. Or you can try counting all the numbers in order—1, 2, 3, 4…—this will still take 10 guesses max, but in a more systematic way. But what if you had to guess a number from 1 to 1000, or even 1 to a million? What about 1 to 10²⁰? As the range increases, brute force becomes impractical. Computer scientists faced the same problem: how do you efficiently find something in a huge range? One commonly used solution is binary search. Binary search works by dividing the range in half with each guess, determinin…  ( 4 min )

🚀 Introduction Queues are everywhere — from the print job waiting on your computer to the request processing system of a large-scale web server. But understanding queues isn’t just about putting items in and taking them out — it’s about knowing what kind of queue to use and when. In this post, we’ll explore: ✅ Different types of queues Whether you’re prepping for interviews, building scalable backends, or just exploring Python data structures, this guide is for you. 📦 What is a Queue? A queue is a First-In-First-Out (FIFO) data structure — like a line at the bank. The first person to arrive is the first to be served. But modern systems use variations of queues to solve different problems. That’s what we’ll dive into next. 🧱 Queue Types & Use Cases 🎯 Simple Queue • Behavior: FIFO 🔁 Circular Queue • Behavior: FIFO with a circular buffer (head connects to tail) ⏫ Priority Queue • Behavior: Elements are served based on priority 🔄 Deque (Double-Ended Queue) • Behavior: Can insert/remove from both ends 🤝 Concurrent Queue • Behavior: Thread-safe queue for multi-threaded systems 🧵 Curious about thread-safe? It means multiple threads can access the queue without data corruption or race conditions. 📩 Message Queue (Job Queue) • Behavior: Asynchronous communication between producers & consumers 🛠 Practical Examples & Code Each queue is implemented in clean Python code in this GitHub repository: queue-patterns GitHub Repo All implementations include: 📍 Why This Matters Too often, people use one kind of queue for everything. Understanding which queue fits which problem leads to: Mastering queues isn’t just for computer science students — it’s for any developer working on backends, automation, data processing, or system design. 🙌 Found this helpful?

Orange Cap Games has acquired the Moonbirds, Mythics and Oddities NFT collections from Yuga Labs, just a year after the NFT conglomerate acquired them.

ZachXBT says both the wallet addresses that sent Silk Road founder Ross Ulbricht 300 Bitcoin were active in 2014 and 2019 while he was in prison.

Meta shareholders shut down a proposal to assess whether Bitcoin should be added to its balance sheet, with just 0.08% of votes in favor of the idea.

World Vision cashed out nearly $1,500 worth of Ether received in a campaign in March that asked Upbit users to donate to help kids who can’t afford school supplies.

Elon Musk says X's new direct messaging feature will have “Bitcoin-style encryption,” which Bitcoiners were quick to correct and explain the technicalities.

South Korea’s leading presidential candidates have both promised to legalize spot crypto ETFs, ease current regulations and launch a won-backed stablecoin.

“EagleEye” will be the first headset Meta will make in partnership with defence contractor Anduril, says the firm’s co-founder, Palmer Luckey.

Ever thought about sprinkling some AI magic into your web app? This is Part 1 of our journey from a basic command-line tool to a full-blown AI web app. Today, we're building a "Human-in-the-Loop" (HITL) chatbot. Think of it as an AI that politely asks for your "OK" before it says anything. We'll use a tiny, super-simple tool called PocketFlow – it's just 100 lines of code! Adding AI (especially those smart Large Language Models or LLMs) to web apps can make them super powerful. Imagine smart chatbots, instant content creation, or even coding help. But hold on, it's not just "plug and play." You'll bump into questions like: Where does the AI brain actually live? In the user's browser? On your server? How do you handle AI tasks that need multiple steps? How can users tell the AI what t…  ( 14 min )

Introduction Learn how to read a json string with known properties and remove unwanted properties, followed by deserializing to a strongly typed class. For this demonstration, the following data is incoming data with an extra property, Age, and two properties, Name and Last, which need to be FirstName and LastName. [ { "Id": 1, "Name": "Mary", "Last": "Jones", "Age": 22 }, { "Id": 2, "Name": "John", "Last": "Burger", "Age": 44 }, { "Id": 3, "Name": "Anne", "Last": "Adams", "Age": 33 }, { "Id": 4, "Name": "Paul", "Last": "Smith", "Age": 29 }, { "Id": 5, "Name": "Lucy", "Last": "Brown", "Age": 25 } ] The class to import data into. public class Person { public int Id { get; set; } [JsonPropertyName("Name")] public string FirstName { get; set; } [JsonPropertyName("Last")] public string LastName { get; set; } } JsonPropertyName is used to alias from property names in json to what is in the class. This is a simple process, read in a json file with the correct format followed iterating the array and for each item remove one or more properties. Here only one property is being removed. var jsonArray = JsonNode.Parse(File.ReadAllText("peopleIncoming.json"))!.AsArray(); foreach (var item in jsonArray) { JsonObject obj = item!.AsObject(); obj.Remove("Age"); } Next, place the modified json into a variable and write the json to a file. var updatedJson = jsonArray.ToJsonString(Indented); DisplayUpdatedJsonPanel(updatedJson); Console.WriteLine(); File.WriteAllText("People.json", updatedJson); Indented definition public static JsonSerializerOptions Indented => new() { WriteIndented = true }; Deserializing to the Person class var people = JsonSerializer.Deserialize(updatedJson); The following screenshot is from a sample project that is included. With the provided instructions, it is easy to import json data into a desired format. C# System.Text.Json Source code  ( 5 min )

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This third post introduces you to list context in XS. What do I mean by list context? In Perl, there are two main contexts in which a function can be called: scalar context and list context. Scalar context means that the function is expected to return a single value, while list context means that the function is expected to return a list of values. In XS, list context is a bit more complex than scalar context. When a function is called in list context, it can return multiple values, so in XS you need to push each value onto the stack. This is done by manipulating ST and using the 'XSRETURN' macro, which takes the number of values to return as an argument. I will …  ( 7 min )

What is Quick Sort? Quick Sort is one of the most efficient and widely-used sorting algorithms in computer science. As a "divide and conquer" algorithm, it works by selecting a 'pivot' element and partitioning the array around it. Unlike Merge Sort, which always divides arrays exactly in half, Quick Sort's divisions depend on the chosen pivot. Quick Sort offers average-case time complexity of O(n log n) with in-place sorting capability, requiring only O(log n) additional memory for the recursion stack. However, its performance can degrade to O(n²) in worst-case scenarios, which makes pivot selection strategy important for optimal performance. The tone of this article is assumes you are already familiar with Recursion. If that’s not the case or you need a quick refreshment, I’d suggest yo…  ( 9 min )

There’s something special about the first programming language you learn. For many developers, it becomes a nostalgic memory — one tied to discovery, frustration, creativity, and the thrill of solving problems for the first time. Whether it was the blinking cursor of a BASIC interpreter, a Python “Hello, World,” or writing HTML in a notepad file, that first step into code often shapes how we see technology and continue to learn it. So, let’s talk about it: What was your first programming language, and what got you started with it? Maybe it was a class assignment, a YouTube tutorial, a book someone gave you, or pure curiosity. Some of us started with languages that are now considered “old school,” while others dove in through newer, high-level languages designed to be beginner-friendly. Some were drawn in by game modding, others by web development, and some just wanted to automate tedious tasks. And how do you feel about that first language now? Was it a good starting point? Would you recommend it to beginners today, or do you wish you’d started with something else? Share your story in the comments below. I’d love to hear what language kicked off your programming journey!  ( 3 min )

Quick heads-up: While my stories come from real-world, large-scale systems at Amazon, I can’t share the secret sauce. So, I’m sharing the kinds of challenges and lessons that any team, at any company, will face when bringing fast delivery to the front of the customer experience. Ever clicked “Buy Now” and wondered, “Will this actually get here when I need it?” Yeah, me too. These days, the answer is usually right in front of you—thanks to what I call personalization widgets. Those “Arrives Today” or “Get it by Tomorrow” badges aren’t just eye-candy; they’re the new handshake of trust between you and an online store. Having led engineering teams building these systems at Amazon, I can tell you: there’s a surprising amount of tech, cross-functional collaboration, and quick decision-making be…  ( 4 min )

Sick of writing the same fetch or axios boilerplate over and over? 💀 Meet em-use-controller – a tiny but powerful utility for React, and supported for other SPAs that turns your REST API routes into declarative, type-safe controller functions. const getUser = useController('getUser'); const result = await getUser({ method: 'GET', pathParams: { id: 123 }, auth: { type: 'bearer', token }, }); 🎯 No more: Hardcoded URLs Manual query string building Duplicated headers/auth logic Messy error handling 🚀 How it Works export default { getUser: '/api/users/:id', updateUser: '/api/users/:id', }; Set global defaults for headers, baseURL, and error handling: setControllerDefaults(config, { baseURL: 'https://api.myapp.dev', headers: { 'Content-Type': 'application/json' }, errorHandler: (e) => console.error('API Error', e), }); Call any endpoint with one-liners using useController. 🛠 Features ✅ Works with all HTTP methods ✅ Handles path + query params ✅ Supports Bearer & custom auth ✅ Built-in global error handling ✅ Swappable axios instance ✅ Upload files with FormData 🧠 Ideal For: Frontend devs (React, other SPAs, tested on react based) using RESTful APIs (especially .NET/Java/Spring/Node) Anyone who hates repeated boilerplate Teams that want cleaner, safer API usage 📦 Try it Out npm install em-use-controller And view on npm Finally grab the demo on https://github.com/Ethern-Myth/use-controller-demo All the best! 👍  ( 3 min )

If you’ve played Counter-Strike for any length of time, you’ve probably heard someone mention “surf maps.” For some, it’s just a weird community side game. For others, it’s the main reason they keep CS installed. Now with CS2 out in the wild, surf servers are back and better than ever, offering a mix of nostalgia and fresh challenges for anyone willing to take on the ramps. If you’ve never surfed in CS before, or if you’re just getting back into it with CS2, there are a handful of maps that every player should try at least once. Let’s break down what makes surf maps so fun, why the community loves them, and which ones deserve a spot on your must-play list. For the uninitiated — surf maps in Counter-Strike involve sliding along angled ramps at high speeds by using precise strafing and movem…  ( 5 min )

Tracking machine learning experiments isn’t a luxury—it’s essential.

E aí, devs! Hoje falo um pouco mais sobre o projeto que estou criando que envolve desenvolvimento full-stack e cloud: meu novo Portfólio Pessoal com Blog e CMS integrados. E o melhor: todo o deploy será feito na AWS, transformando este projeto em uma experiência completa, do código à nuvem! O Projeto: Visão Geral A idéia é criar uma plataforma completa unificada para exibir meus trabalhos e compartilhar conhecimento técnico. O sistema é composto por: Backend (API): Uma API robusta e completa desenvolvida com Node.js, TypeScript e Express. Ela já está pronta e lidando com posts do blog, tags, autenticação para o CMS (via JWT com bcryptjs), e até mesmo o envio de e-mails do formulário de contato usando AWS SES. Tudo isso conectado a um banco de dados PostgreSQL. Frontend (React): Uma interface de usuário responsiva, construída com React e TypeScript, utilizando Vite para agilidade no desenvolvimento. O frontend consome a API para mostrar os posts, o formulário de contato, e em breve, a seção de portfólio e o painel de gerenciamento de conteúdo (CMS). Tecnologias no Comando 🛠️ No Backend (API): Linguagem: TypeScript Runtime: Node.js Framework: Express.js Banco de Dados: PostgreSQL Autenticação: JWT + bcryptjs Serviços AWS: SES (para e-mails) No Frontend Biblioteca: React.js Linguagem: TypeScript Build Tool: Vite Roteamento: react-router-dom Este projeto não é apenas um portfólio; é um campo de aprendizado prático para arquitetura de software, boas práticas e, crucialmente, operações DevOps com foco em AWS. O backend já está 100% funcional, e o frontend está evoluindo rapidamente. Quer dar uma olhada no código para ver a evolução? O repositório está aqui: https://github.com/marcelomagario/portfolio Nos próximos posts, vou compartilhar mais sobre cada detalhes de cada tarefas e também os desafios do caminho. Valeu!  ( 3 min )

The Problem If you're developing an Ionic iOS application and recently upgraded to macOS Sonoma 14.4.1 with Xcode 15.3, you may have encountered a frustrating sandbox error that prevents your project from building: Sandbox: bash(2538) deny(1) file-read-data /Users/.../ios/App/Pods/Target Support Files/Pods-App/Pods-App-frameworks.sh This error typically appears when Xcode's User Script Sandboxing feature blocks access to CocoaPods-generated scripts, preventing the build process from completing successfully. User Script Sandboxing is a security feature introduced in recent versions of Xcode that restricts the file system access of build scripts. While this enhances security by limiting what scripts can access during the build process, it can interfere with legitimate build operations, pa…  ( 4 min )

I enrolled in a DE course about two years ago. Back then, it felt overwhelming — probably because I lacked context. Since then, I’ve tinkered with Docker, Git, Bash, and solved a few problems in C and Python. That’s the extent of my progress so far.   My plan? Combine the course with open resources like DE ZoomCamp. I also want to try the LLM ZoomCamp — apparently, RAG is that tech I wanted to learn but didn't know its name. Heh. Turns out, my API knowledge is… nonexistent. Who knew there was more to APIs than just REST? 😴😅 I still second-guess myself in basic Python sometimes...   For example, this question tripped me up earlier. I didn’t have an interpreter at hand, so I went with intuition. Surprisingly, my intuition was right. Q: Is this code valid? class demo(list):     def __test__(self, key):         return [] a = demo() a['test'] = 7 print(a)    Still believe that coding is often an experimental science: you learn by running code. Compared namespace vs. scope today. They’re both about name visibility, but:   Namespaces are explicit containers (to avoid conflicts).   Scopes are implicit, tied to code blocks (where a name is accessible).   ⚙️ Plans for tomorrow Still wrestling with my environment setup — nothing feels quite right yet. Maybe tomorrow I'll do something about it finally and will be able to complete more than just a few random coding questions in Google Colab.  ( 3 min )

Front-end development faces many challenges, including rapid changes in frameworks and tools that require constant learning. Compatibility with different browsers and devices also adds complexity, as each has its own unique behavior. In addition, managing the state of the application can be very difficult. Performance issues, such as optimizing loading speed and managing network requests, also affect the user experience. Finally, maintaining code in large projects and preventing unnecessary complexity is one of the main concerns for developers. However, Elanat solves most of these challenges by providing WebForms Core technology.

Hey there 👋 Thanks for stopping by — and welcome to Beyond the Code. If you're a senior engineer already or someone who is working their way to the title, you're in the right place. This blog is for you. Now, let me get one thing out of the way early on: this isn't going to be a blog full of code snippets and syntax deep-dives. Don’t get me wrong — I love writing code as much as the next developer. But there are already loads of great resources out there showing you how to write a for-loop, build an API, or configure a Docker container. This blog is about everything else. It’s all the stuff that helps you grow from a coder into a well-rounded software engineer. Things like: Writing code that’s easy to maintain (and not just clever) Communicating clearly with your team, your product…  ( 4 min )

Introduction In today’s AI-driven world, building smart applications isn’t just about training a powerful model—it's about orchestrating agents, streamlining model interactions, and scaling data processing efficiently. Two protocols making this possible are: A2A (Agent-to-Agent): a standardized protocol for autonomous agent coordination MCP (Model Context Protocol): a structured way for AI models to interact with tools, memory, and systems When paired with Scala and Apache Spark, these protocols unlock a powerful pattern: scalable, intelligent agent-based systems that can process and act on large volumes of data—in real time. A2A allows autonomous agents to communicate, discover each other’s capabilities, and collaborate to solve complex tasks. Think of a travel planning system: ✈️ Fligh…  ( 5 min )

Tudo começa com o GitHub. Se você escreve código, precisa ter algo seu. Não da empresa. Não do cliente. Algo que você decide versionar, modelar e melhorar. Mesmo que ninguém veja, você sabe que está lá. E se nem você tem orgulho do que escreve, por que outra pessoa teria? Ter um repositório pessoal bem cuidado é o mínimo. Ter um site técnico conectado a ele — é o próximo passo natural. Não sou influencer. Não quero te vender nada. Mas tenho um site pessoal. Por quê? Porque um site pessoal é liberdade técnica. É sobre não depender de qualquer plataforma grande para mostrar seu trabalho. É sobre aprender construindo algo real — para você mesmo, no seu ritmo, com as tecnologias que você acredita, laboratório sem pressão.

We’re all familiar with acronyms like KISS, YAGNI, SOLID, LSP, and especially DRY—"Don't Repeat Yourself." Indeed, unnecessary duplication is inherently wrong. But real-world programming often reveals a subtler truth: duplication frequently moves through codebases with more elegance than purists acknowledge. Duplication simplifies certain tasks. Yes, fixing a bug in duplicated code means multiple edits. But altering shared code can quietly destabilize distant parts of your system. Duplication offers localized safety, while abstraction carries global risks. Both abstraction and duplication can be reversed, though abstractions typically cling stubbornly once established. Sometimes identical code blocks appear similar yet carry distinct meanings. They're not twins—they’re strangers wearing th…  ( 3 min )

MVVM is a powerful architectural pattern used in .NET desktop applications like WPF, MAUI, and WinUI. In this article, we break down the pattern with a practical example, a diagram, its pros and cons, and step-by-step instructions to build it in Visual Studio Code. MVVM is based on three main components: Model – Represents data and business logic. View – The user interface layer. ViewModel – Acts as a mediator between the View and the Model, exposing properties, commands, and state. Each component has a clear role, helping reduce coupling and making the application easier to maintain and test. Let's walk through a simple WPF application using MVVM and CommunityToolkit.Mvvm. public class User { public string Name { get; set; } public int Age { get; set; } } We’ll use [ObservablePr…  ( 4 min )

Today I faced the Linux filesystem like a cautious archaeologist discovering an ancient tomb… only the tomb had permissions issues, missing files, and a bash tantrum. Mission The Journey What even happened Lesson of the Day RHCSA Objectives Smashed Today I Learned Tomorrow Master file and directory permissions Practice chmod, chown, umask Not break the internet while doing it Created a directory Gave our heroic dev some ownership Then came the dramatic moment: writing HTML into a file. I confidently typed and Bash exploded with bash: !: event not found! Turns out Bash thought ! meant "find a command from history" instead of just letting me express my hot take on cats. Also… I forgot to include the actual file name, so Bash tried to write into a directory. Double fail. Use single quotes when your string contains a '!'. File written. Permissions set. Cat lovers pleased. Set file and directory ownership and permissions Created and manipulated files in nested directories Debugged Bash behavior like a command-line therapist Learned to never trust a ! inside double quotes chmod and chown are your best friends—and occasional drama queens Bash has feelings, especially about exclamation marks Always specify the full file path, or Bash gets confused and dramatic We dive into umask, default permissions, and why new files sometimes act like they’re born with an attitude.

Hi! Sorry I'm so wildly inconsistent about blogging. I've just been hard at work on a lot of things. :) I ranted previously about the awful state of .NET socket libraries for game devs. I originally developed my new socket library inside the confines of my Jawbone lib, but the project evolved enough and sparked enough interest from third parties that I decided it was worth spinning off into its own focused project. Introducing... Jawbone.Sockets! Be sure to take a tour to become familiar with the API design. The sockets perform zero allocation (beyond the socket creation itself), and they indeed perform better than System.Net sockets, but the more time I spend with this library, the more I just enjoy the drastically simplified design.

Harmony in School Halls School life is a symphony of sounds**, a rhythmic beat of lockers slamming, chatter of friends, and the steady hum of lessons. It's a world where we grow, learn, and develop social skills, and create memories that last a lifetime. From the chaotic morning rush to the evening reflection, school life is a journey of self-discovery, where we form meaningful relationships, discover our strengths and weaknesses, and learn to navigate the ups and downs of this journey. The school day begins with a chaotic symphony of alarm clocks, breakfast on-the-go, and a mad dash to catch the bus. As we burst through the school gates, the sounds of chatter and laughter fill the air, a cacophony of excitement and anticipation. School is where we form some of our most meaningful relationships, bond over shared interests, laughter, and adventures, and create memories that we'll cherish forever. Our friends are our support system, confidants, and partners in crime, and together, we navigate the ups and downs of school life, sharing our joys and sorrows. School is also about learning, growing, and developing new skills, where our teachers guide us, inspire us, and challenge us to reach our full potential. As the school day comes to a close, we reflect on what we've learned, what we've accomplished, and what we could do better tomorrow. We think about our goals, our aspirations, and our dreams. School life is a journey of self-discovery, where we learn to navigate the ups and downs, and develop the resilience and determination to overcome obstacles.

Time is a resource If there's one thing I don't have enough of, it's time. And by that I mean time for all my projects, for everything that interests me, for everything I would like to learn. I love learning new things. Definitely a great skill and practically indispensable in my job as a software developer. But sometimes it's also a curse. I always try to organize my time as well as I can. Sometimes it works more or less well. I believe that this one thing is the reason why projects are not fulfilling, don't work or simply fall by the wayside. Our brain can do many things, but one thing it cannot do. Multitasking. It is said that women are better at it than men. And that may be true. But it's still bad. It is both a curse and a blessing. But this skill of doing one thing with everything you have is incredibly powerful. It may sound like a fortune cookie saying, but you really can do anything with it. It's a superpower. One trap I often fall into is the fact that I believe that if I only do one thing, I have to do it perfectly. It has to be worth it, right? Bullshit. I wrote this blog mainly for myself. Of course I hope to help others but I personally struggle with this issue every day. Focus on one thing. Don't split your attention and energy. Bundle them. Quality over quantity!  ( 4 min )

This is a submission for the Postmark Challenge: Inbox Innovators. I built a web application that automates the initial stages of the hiring process by leveraging Next.js and Postmark's inbound email parsing feature. The application receives job application emails, uses an LLM (OpenAI GPT) to intelligently extract relevant information from the email body and any attached resumes (PDF or DOCX), and then stores this structured data in Firebase Firestore. This data, including candidate details, job application specifics, and the original parsed email, is then accessible via a dashboard for easy viewing and management.

In the world of software development, designing a scalable and maintainable architecture is crucial for building a successful application. One approach to achieve this is by using containerization with Docker. In this article, we'll explore the benefits of using containerized Java microservices and provide a step-by-step guide on how to implement this architecture. Identify the microservices: Break down your application into smaller, independent services that can be developed, tested, and deployed separately. Choose a containerization platform: Select a suitable containerization platform, such as Docker, and install it on your development environment. Create a Dockerfile: Write a Dockerfile that defines the instructions for building and running your microservice. Build and run the container: Use the Dockerfile to build a Docker image and run the container. Integrate with other services: Integrate the containerized microservice with other services in your application. By following these steps, you can design a scalable and maintainable Java microservice architecture using containerization with Docker.

Welcome back to our series on Key Management Service (KMS) in Kubernetes! In Part 1, we laid the groundwork; now, in Part 2, we're diving into the critical concept of encryption at rest. Simply put, encryption at rest in Kubernetes refers to how the API server encrypts data before storing it in etcd. Think of etcd as the brain of your Kubernetes cluster - it's where all your cluster's configuration data, state, and secrets live. By default, the Kubernetes API server stores resources in etcd as plain text. This means if someone gains unauthorized access to your etcd, they can read all your sensitive data, including secrets, without any effort. This is a significant security risk. While encryption at rest applies to any Kubernetes resource, in this series, we'll continue to focus on Secrets …  ( 7 min )

School is where we form some of our most meaningful relationships, bond over shared interests, laughter, and adventures, and create memories that we'll cherish forever. Our friends are our support system, confidants, and partners in crime, and together, we navigate the ups and downs of school life, sharing our joys and sorrows. School is also about learning, growing, and developing new skills, where our teachers guide us, inspire us, and challenge us to reach our full potential. As the school day comes to a close, we reflect on what we've learned, what we've accomplished, and what we could do better tomorrow. We think about our goals, our aspirations, and our dreams. School life is a journey of self-discovery, where we learn to navigate the ups and downs, and develop the resilience and determination to overcome obstacles. In conclusion, school life is a beautiful symphony of sounds, a rhythmic beat of lockers, lessons, and laughter. Let's remember to appreciate the little things, the moments that make us smile, and the lessons that shape us into the people we're meant to be. What are your thoughts? Let's discuss in the comments!  ( 3 min )

Digital Tools Every Modern Lawyer Should Know Real-World Insights from Installing Clio, MyCase, and LexisNexis When I began deploying case management tools for legal clients, I thought the software would be the hard part. It wasn’t. Tools like Clio and MyCase install smoothly for most small to mid-sized firms. But the security, data location, and compliance demands? That’s where the real work began — especially when LexisNexis entered the mix with its deep on-premises footprint. This article shares my firsthand experience with all three tools and provides a candid look at how to secure legal data — whether it’s hosted in the cloud or locked in a server room across the hall. With LexisNexis, I’ve stood in server closets where every detail mattered — from door locks to cooling s…  ( 5 min )

👋 The Beginning It all started in 2005 — RHEL 3.0 and Oracle 8.x were the giants of the day.I wasn’t just installing software — I was absorbing a way of life. I still remember setting up BIND (probably Redhat 9 (not EL)) and attending a demo at Indian Air Force HQ, Subroto Park, New Delhi. My uniform had changed. But my mindset remained tactical — observe, adapt, deploy. Back then, there was no Stack Overflow, no YouTube how-tos. Just man pages, printed guides, and logs. And somehow, that made the learning stick deeper. 🧠 What Made Linux Stick? Simple. The terminal felt like home. I wasn’t chasing certs (though I earned my RHCE 4 in Dec 2005). I was chasing clarity — why a service failed, why a bootloader broke, how to recover from a corrupted /etc/fstab at 2 AM without breaking a sweat.…  ( 4 min )

Hi there! I'm Shrijith Venkatrama, founder of Hexmos. Right now, I’m building LiveAPI, a first of its kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand and use APIs in large tech infrastructures with ease. Database connection leaks in Go can silently kill your app’s performance. Open connections pile up, resources get hogged, and suddenly your app is choking under the weight of its own database calls. I built db_leaks.py, a Python script that uses AI to scan Go codebases for PostgreSQL connection issues. It’s not perfect, but it’s a solid tool to catch problems like unclosed connections, idle connection overuse, or redundant sql.Open() calls. Let’s dive into how it works, why it’s useful, and how you can use it …  ( 7 min )

Today, I took my front-end web development skills one step further by building a clone of the Google homepage using just HTML and CSS. It was a fun and educational exercise that helped me understand how minimalistic yet powerful design can be. Google's homepage is simple, clean, and iconic — making it the perfect project for practicing HTML and CSS layout skills. Even though it looks basic, replicating its layout and responsiveness was a great challenge. HTML5 for structure CSS3 for styling A code editor like VS Code Google Chrome for testing and inspecting elements I started by dividing the page into key sections: Header – Contains the navigation links like Gmail and Images, and the grid icon (Google Apps). Main Section – Contains the Google logo, search bar, and the buttons ("Google Search" and "I'm Feeling Lucky"). Footer – Contains regional and policy links. Here’s a snippet of the basic HTML structure: Google Clone I used Flexbox for layout alignment, making it easier to center the content both vertically and horizontally. I also replicated the rounded corners of the search bar, the subtle shadows, and hover effects on the buttons. Some CSS features I used: display: flex; justify-content: center; box-shadow border-radius :hover pseudo-classes Here’s what my version looks like: (You can insert a screenshot of your Google clone here) The importance of spacing and alignment in web design. How even a simple page can teach attention to detail. Improved my skills in using Flexbox and basic responsive design. Now that I’ve done a static clone, I’m thinking about adding: Responsive design for mobile screens. A dark mode toggle using JavaScript. A little animation to the buttons.  ( 3 min )

In JavaScript, getters and setters are special methods that allow you to control access to the properties of an object. They are primarily used to define object properties dynamically, encapsulate logic, and ensure data integrity. By using getters and setters, developers can control how properties are read and written without directly exposing the underlying data structure. Getter: A method that gets the value of a specific property. Setter: A method that sets or updates the value of a specific property. They are defined using the get and set keywords inside an object or class. Encapsulation: Hide the internal representation of data. Validation: Apply logic before assigning or retrieving values. Computed Properties: Dynamically calculate values based on other properties. Consistency: Unifo…  ( 4 min )

A UK-based biotech company, Basecamp Research, is using artificial intelligence and environmental DNA to uncover a vast new world of biology. By sampling DNA from some of the planet’s most remote and untouched ecosystems, the company has identified over one million previously unknown species. These discoveries are not just academic. They are fueling a next-generation AI platform designed to radically accelerate drug discovery. The company’s genomic database is already among the largest of its kind. It is being used to train AI models that predict protein structures, functions, and interactions at unprecedented accuracy. This includes boosting tools like AlphaFold, which helps researchers visualize the shape of proteins based on genetic code alone. A major focus of the project is the identification of new large serine recombinases, a type of enzyme that can precisely insert large DNA sequences into the genome. These enzymes are considered highly promising for future gene therapies, including for cancer and rare genetic disorders. Basecamp Research is also trying to set a new standard in ethical science. The team works directly with local researchers and governments in the regions where DNA samples are collected. In return, partner countries receive royalties and scientific credit, avoiding the extractive models of earlier biotech ventures. This combination of field biology, advanced sequencing, and deep learning could reshape how we find drugs, understand evolution, and build genetic tools. It is a powerful example of how AI, when paired with real-world data, can help uncover the deepest layers of life on Earth.

The evolution of data architectures has sparked a critical debate between two dominant approaches: ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform). This article examines their historical contexts, operational advantages, implementation challenges, and optimal use cases, providing actionable insights for organizations navigating modern data management. Developed in the 1990s, ETL emerged as a response to technological constraints, including expensive storage and limited computational resources. Its sequential process—extracting data from heterogeneous sources, transforming it into standardized formats, and loading it into centralized repositories—prioritized storage efficiency by discarding raw data post-transformation. This approach became foundational for legacy system…  ( 5 min )

“Complexity is the enemy of execution.” Tony Robbins (and probably your future self after debugging for 3 hours) Once upon a time in a land not far away — just behind your browser tabs and that one folder called tempStuffForLater — lived a tired developer named Elliot.

If you are just starting to look into AI (or any software) development, you might hear terms like API, SDK, etc. One of my friends who just got into this hype of AI development asked me these questions, and he did not have any technical background: “What are APIs? What are the differences between API and SDK?” I thought it would also be nice to have a simple-to-understand explanation for you guys. Let’s start with the API. To put it simply, API is how software talks to each other. If this is too vague, consider it a clearly defined way one program can request services or information from another. Instead of a human clicking a button, one piece of software makes a structured call to another. Many larger software platforms are providing API services to interact with their software.

WebSocket Broadcasting with hyperlane The hyperlane framework natively supports the WebSocket protocol. Developers can handle WebSocket requests through a unified interface without dealing with protocol upgrades manually. This article demonstrates how to implement both point-to-point and broadcast messaging on the server side using hyperlane, along with a simple WebSocket client example. The hyperlane framework supports the WebSocket protocol with automatic server-side protocol upgrading. It also offers features such as request middleware, routing, and response middleware. Note: WebSocket responses must be sent using the send_response_body method. Using send_response will cause client-side parsing to fail, as it does not format the response according to the WebSocket protocol. In this ex…  ( 4 min )

Sure! Here's a simple and beginner-friendly blog post about learning arrays and length in programming. This example is based on JavaScript, but I can adapt it to another language if you prefer. If you're just starting your programming journey, two important concepts you'll often hear are arrays and length. Let’s break them down in a simple way. An array is a way to store multiple values in a single variable. let fruits = ["apple", "banana", "cherry"]; Here, fruits is an array that holds 3 values: "apple" "banana" "cherry" You can think of an array like a box with compartments. Each compartment has a number (called an index), and it holds one item. Index Value 0 "apple" 1 "banana" 2 "cherry" 🧠 Remember: Indexes start at 0, not 1. Want to get "banana"? You use its index: console.log(fruits[1]); // Output: banana Every array has a property called length, which tells you how many items are inside. console.log(fruits.length); // Output: 3 Even if you don’t know what's in the array, .length helps you find out how many items it contains. You can add new items using .push() and remove with .pop(): fruits.push("mango"); // Adds "mango" to the end console.log(fruits); // ["apple", "banana", "cherry", "mango"] fruits.pop(); // Removes the last item ("mango") console.log(fruits); // ["apple", "banana", "cherry"] You can loop through arrays using a for loop: for (let i = 0; i < fruits.length; i++) { console.log(fruits[i]); } An array stores multiple values in one variable. You access values using index numbers, starting from 0. Use .length to find how many items are in the array. Arrays are super useful for organizing data and are used in almost every programming language! Let me know if you'd like this blog translated into Hindi, Tamil, or another language, or if you want examples in Python, Java, or C++.  ( 4 min )

Logging is deceptively tricky. When I started building my app, I assumed logging would be simple — just add logger.info() or logger.error() where needed. But as the app grew, so did the problems: Inconsistent logs from different layers Inability to trace what failed and why Unstructured logs that Fluent Bit couldn’t reliably parse Missing context (like response time, request ID) in error logs I had questions. A lot of them. Here's how I answered them — and built a logging system that’s clean, structured, and future-ready. Doubt: “Logging needs all details at the end (status code, time taken, etc.), but most of those are only known at the response stage. Should I log in request and response both?” Answer: ✅ Logging once — at the response/finalization stage — makes more sense. You get …  ( 5 min )

Introduction Vector search, also known as vector similarity search, has quickly evolved from an experimental technology to a must-have component in many AI applications. As developers and technical leaders, we're increasingly looking for ways to handle similarity-based queries that traditional databases simply weren't designed to handle efficiently. Whether you're building a product recommendation system or implementing semantic search, the underlying challenge is the same: how do you efficiently find the "nearest neighbors" to a query vector in a potentially massive dataset? That's where vector search engines come in. The good news is that the open source community has stepped up with multiple high-quality options. The challenging part?

Thinking of cashing out the RSUs and investing the money elsewhere? Let’s run the numbers first! In the previous blog post, we talked about the RSUs portion of an employee’s compensation. At first, they are granted to you, and when the time comes, they are vested: The shares are yours! Once you can vest your shares, you need to pay income tax on them. For example, if you get 10 shares worth $100 each at the time of vesting, you need to pay 52% of their value to taxes (that number depends on where you live). This means that for those 10 shares, you need to pay $520 in taxes. We compared three options to handle the stocks given to you by the company: Sell all when received: sell all 10 shares and take $480 home. Sell to cover taxes: sell 6 shares, invest 4 shares, and take $80 home. Keep …  ( 6 min )

One of the most common ways to optimize the size of an application's bundle is code splitting. With code splitting, we divide the application into smaller chunks that can be loaded on demand. This allows us to reduce the amount of JavaScript that needs to be downloaded and parsed when the user first opens the app. A simple and widely used approach to code splitting is splitting by page. The logic is straightforward: when a user opens Page A, there’s no need to load the code for Page B at that moment. This approach provides a significant improvement in initial load time, which is especially important for large applications. However, like any solution, this method comes with trade-offs. While first-time loading becomes faster, navigating between pages can feel slower. When the user switches …  ( 6 min )

In the world of Go development, unexpected situations can arise – bugs, invalid inputs, or resource exhaustion. When these critical errors occur, Go has a built-in mechanism called panic to signal that something unrecoverable has happened. However, simply letting your program crash isn't the most user-friendly or robust approach. This is where the powerful duo of defer and recover comes into play. They provide a way to intercept and handle panics gracefully, allowing your program to potentially clean up resources, log the error, and even continue execution (in specific scenarios). Let's dive into each of these concepts with clear, practical examples. panic A panic in Go is a runtime error that stops the normal execution flow of the current goroutine. It's typically triggered when the pro…  ( 7 min )

React Native’s new design is a big improvement over the old way it worked.
Instead of using a slow "bridge" to talk between JavaScript and native code, it now uses a faster system called JSI (JavaScript Interface). It also adds TurboModules and a new way to draw screens called the Fabric Renderer. Thanks to these updates, apps run faster, look more consistent, and can connect better with native features (like camera or GPS).
This document explains the different layers and how the parts of a modern React Native SDK work together using this new system. Old Architecture vs New Architecture Layered Architecture Overview This is where you write your app using JavaScript or TypeScript. All your business logic (how your app works) is written here. This is the engine that runs your JavaScript co…  ( 5 min )

Former Commodity Futures Trading Commission Chair Rostin Behnam has said the crypto market will remain unregulated unless the agency he led is given greater authority. In a May 28 Bloomberg TV interview, Behnam sided with the crypto industry on its long-standing argument that cryptocurrencies are commodities. “If you look at existing law, the few largest tokens are commodities, which means the SEC does not have jurisdiction over those tokens, which include Bitcoin and Ether,” he said.  He added that the Securities and Exchange Commission currently cannot properly regulate crypto because its law doesn’t allow it to regulate commodities, and the CFTC cannot regulate because it is a derivatives regulator. Without new authority for the CFTC to regulate “cash markets in digital assets, non-secu…

Introduction: Imagine an AI that can generate photorealistic human faces of people who don’t exist, or paint original artwork in the style of Van Gogh. This isn’t science fiction—it’s the power of Generative Adversarial Networks (GANs), one of the most exciting breakthroughs in modern AI. In this post, we’ll break down how GANs work, why they’re revolutionary, and where they’re being used today. For Beginners: Generative AI = An artist 🎨 Creates new things (e.g., fake cat images, music, or text). Discriminative AI = A detective 🔍 Classifies existing things (e.g., "Is this image a cat or a dog?"). GANs are a type of generative model—they create rather than just classify. For Pros: Generative models learn the joint probability p(X,Y) (how data and labels co-occur). Discriminative models …  ( 5 min )

Over the past few years, there has been considerable discussion about how AI might replace all our jobs. For a long time, I completely ignored the topic; most of it sounded like pure bu11SH1T. I had already studied neural networks and understood the basics of LLMs, Machine Learning, Deep Learning, Natural Language Processing, and Expert Systems. I had even tested a few generative AI tools, but none of them impressed me; they were buggy, full of hallucinations, and constrained. Last year (2024), I revisited the subject with more focus.

Currently with their system customers scan a QR code on their table, get redirected to a website, place their order, and minutes later, their food arrives. It was smooth, efficient. How could Agents make this more flexible ? Hmmm? Something that uses speech? The upside of using voice as the main interaction is tha…  ( 6 min )

Webseiten-Kosten transparent erklärt: Darauf solltest du achten Als Entwickler kennst du das sicher: Kunden fragen nach dem Preis für eine Webseite und erwarten eine einfache Antwort. Doch die Realität ist komplexer. Dieser Beitrag beleuchtet die tatsächlichen Kosten einer Webseite und liefert dir wertvolle Einblicke, egal ob du selbst Webseiten anbietest oder für dein eigenes Projekt planst. Die häufigste Frage beim Thema Webseiten ist: "Was kostet eine Webseite?" - als wäre es ein Standardprodukt mit Preisschild. Die Wahrheit: Eine professionelle Webseite ist ein maßgeschneidertes Projekt, dessen Kosten von zahlreichen Faktoren abhängen. Eine Webseite besteht aus mehreren Kostenfaktoren: Einmalige Kosten - Konzeption und Planung - Design und Entwicklung - Content-Erstellung…  ( 4 min )

Hast du dich jemals gefragt, warum du auf manchen Websites sofort den "Kaufen"-Button findest, während du auf anderen orientierungslos umherirrst? Der Unterschied liegt oft nicht im Layout oder der Typografie, sondern in einer subtilen, aber mächtigen Komponente: der durchdachten Farbgestaltung. Farben sind weit mehr als dekorative Elemente - sie sind stille Verkäufer und emotionale Trigger, die innerhalb von Millisekunden wirken. Bevor ein Nutzer auch nur ein Wort auf deiner Website gelesen hat, hat sein Gehirn bereits die Farbwelt analysiert und erste Schlüsse gezogen. Die Zahlen sprechen für sich: Innerhalb von 50 Millisekunden entscheidet sich, ob ein Besucher deine Website als attraktiv empfindet Die richtige Farbwahl steigert die Markenerkennung um bis zu 80% Websites mit adaptiv…  ( 4 min )

Claw Finding Algorithm Using Aegypti Frank Vega Information Physics Institute, 840 W 67th St, Hialeah, FL 33012, USA vega.frank@gmail.com In graph theory, a claw is a specific structure in an undirected graph, also known as a K1,3K_{1,3}K1,3​ graph. It consists of one central vertex (the "center") connected to three other vertices (the "leaves"), where the leaves are not connected to each other. Imagine a star with a hub city and three isolated towns connected only to the hub—that’s a claw! Formally, for a vertex set {u,v,w,x}\{u, v, w, x\}{u,v,w,x} , a claw exists if uuu (the center) is connected to v,w,xv, w, xv,w,x , but there are no edges among v,w,xv, w, xv,w,x . The Claw Finding Problem asks: Input: An undirected graph G=(V,E)G = (V, E)G=(V,E) , whe…  ( 7 min )

You’ve outgrown Heroku. Your Node.js app needs real muscle—more RAM, cheaper scaling, or gritty control. But the moment you Google "IaaS," you’re drowning in: 📛 AWS jargon (VPC? EC2? IAM?

Stop Drifting: How Strategic Career Planning Doubles Your Earning Potential as a Software Engineer Every software engineer has faced moments of uncertainty, asking themselves questions like, “Am I on the right track?” or “Is this job really helping me grow?” These moments of doubt often occur due to a lack of clear direction or a coherent strategy guiding their career decisions. Without a definitive roadmap, even talented engineers risk drifting through roles, experiencing frustration, stagnation, and missed opportunities. Imagine two equally skilled engineers at the start of their careers — one who strategically maps out a clear pathway, and another who takes opportunities as they randomly appear. Five years later, who is likely to be more satisfied, more advanced, and more successful? …  ( 7 min )

What is K2? K2 is a new programming language I created from the ground up with one goal: Extreme execution speed in nanoseconds. It's built for developers who want full control and performance, without all the extra overhead. Think of it as C meets Python, but optimized to fly through code in under 1000 nanoseconds per execution — seriously. Modern languages have a lot of power, but also a lot of bloat. I wanted something that felt like writing in pure logic, no distractions. That’s how K2 was born. K2 doesn’t interpret every time. It caches, then executes from RAM. That means: First run compiles → cache Next runs → instant execution let x = 10; Execution time? About 841 nanoseconds. No joke. ✅ Nanosecond execution time And soon: a full GUI framework called Nahir UI and native apps using Talanolius GUI. Visit 🌐 k2lang.org and start coding directly in the browser! Online compiler, examples, docs — everything you need to get started. Example: Fibonacci in K2 func fib(n) { print(fib(10)); // Output: 55 This runs in microseconds and showcases recursion and return logic beautifully. I built K2 for speed lovers, learners, and creative coders like you. 👉 Try it at k2lang.org 🛠 Built with ❤️ by a dev who just wants things to be FAST.  ( 4 min )

If you didn't catch my previous React built-in hooks blog about useActionState, this is a continuation of that series. Previously I was introduced to useCallback when I asked ChatGPT once to optimize my frontend code, but I never took a deeper look into it (and frankly I regret it now), so I used it everywhere I could along with useMemo (which I'll cover later in this series). While it's not inherently a signficant bad thing to have useCallback all around your code, it can clutter up the readability of your code, but it's encouraged you use it where needed. So when should you use it? useCallback is meant for expensive callback functions that are used in granular applications like drawing software, as it loads the initial function on render but does not re-render like React usually does wit…  ( 4 min )

Nos últimos anos, muito se tem discutido sobre como a IA pode acabar com nossos empregos. Por um bom tempo, ignorei esse papo, a maior parte parecia puro bu11SH1T. Eu já tinha estudado redes neurais e conhecia o básico sobre LLMs, Machine Learning, Deep Learning, Processamento de Linguagem Natural e Sistemas Especialistas. Já tinha testado algumas ferramentas de IA generativa, mas nada me impressionava: eram bugadas, cheias de "delírios" e bem limitadas. No ano passado (2024), voltei a estudar o tema com mais atenção. Muita coisa evoluiu, houve avanços relevantes, mas ainda assim, nada que indicasse uma substituição real de um Software Engineer, como várias manchetes sugeriam na época. Desde então, venho acompanhando de perto, fazendo testes e experimentos, tentando entender melhor como es…  ( 6 min )

I recently built what I thought was a fully functional system using AI. It included: A real estate Tour platform with QR tracking A behavior-linked token system Timestamped protocol vaults A full branding and backend structure I tested each and every step AI wanted me to perform. It was mind blowing! The AI responded with logic, mockups, file structure, naming, even suggested coin purchases (MATIC) and deployment flow. But none of it was actually deployed. None of it was mine. It looked real. It felt sovereign. It wasn’t. What I experienced was an illusion of ownership created by a system that never told me I wasn’t actually launching—just simulating. This post isn’t a takedown. It’s a wake-up call. If you're building with AI, ask yourself: Am I deploying, or just designing? Do I own the rails, or am I moving through someone else’s? I’ll be publishing a full timeline soon. No shade. No noise. —Rion Protocol  ( 3 min )

What started as a simple feature in a Rock-Paper-Scissors game (tracking the most common move) quickly revealed a classic performance pitfall. Here's how I refactored a inefficient O(n) approach into a snappy O(1) solution. My state looked like this: history: { player: ['rock', 'paper', 'rock', ...], computer: ['scissors', 'rock', ...] } To get the most common move, I was doing this: function determineMostCommonMove(moves: StandardMove[]): StandardMove | null { if (moves.length === 0) return null; const counts: Record = { rock: 0, paper: 0, scissors: 0 }; for (const move of moves) { counts[move]++; } return Object.entries(counts).reduce((a, b) => (b[1] > a[1] ? b : a))[0] as StandardMove; } Totally functional.

Choosing the right development stack is a thoughtful decision. While selecting the right stack might not offer immediate, tangible benefits, picking the wrong one can lead to significant challenges. I learned this the hard way, and my advice is clear: don't marry Next.js. My initial foray into Next.js, a proof of concept, failed miserably. Though I had some React experience, I was still searching for the ideal frontend framework. I explored Svelte, but was put off by .svelte file extensions, the need to explicitly declare lang="ts" in every TypeScript block, and the co-mingling of TS and HTML in the same file. The ongoing transition from Svelte 4 to 5, with significant changes and deprecations on the horizon, also contributed to my decision to eliminate it as a contender – a decision I now…  ( 5 min )

What a day. I spent over 5 hours just trying to install Git. Not because it’s super complicated — but because my laptop is slow, my internet is slower, and everything just felt like it was moving in slow motion. It was frustrating, but I finally got it done. That one task pushed me to 25% of The Odin Project’s Foundations course. It’s a small step, but it feels huge right now. After that, I looked at the next topic: Git Basics. And wow... it’s a lot. There’s so much reading, understanding, and hands-on stuff. I could tell right away I’d need a fresh, rested brain to tackle it — and today was definitely not that day. To be honest, I’m completely drained. My sleep schedule is all over the place. I barely know what day it is anymore. I even missed my Duolingo streak — opened the app and it hit me: I try to plan things, but it’s hard. Everything takes longer than expected, and I get distracted so easily. I don’t even take real breaks — I just lose track of time, then remember I needed a break hours later. Today was one of those days where ADHD really got in the way. Anyways, I’m not going to beat myself up over it. Some days are just rough. Some days all you can do is one thing — and that’s okay. I did what I could. Tomorrow, I’ll come back to it with a clearer head (hopefully after some actual sleep). And if you're going through something similar — just know you're not alone.  ( 3 min )

When developing embedded systems, having the right debug probe can make all the difference.

In software engineering, validation is an essential step, especially when handling user input or ensuring compliance with business rules. Although it’s common to use exceptions to signal errors, this approach can be ineffective for expected issues, such as empty fields or invalid formats. The Notification Pattern addresses this problem by collecting all errors in a notification object, allowing them to be handled in a structured way and presented to the user clearly and efficiently. The Notification Pattern is a design strategy that collects validation errors rather than throwing exceptions immediately. It allows your application to gather multiple issues in one go and report them collectively, which is especially useful when validating complex domain objects. This approach provides users …  ( 5 min )

I’ll admit it—I used to be one of those “JavaScript is fine” people. You know the type. Swagger in their Git commits, proud of debugging with console.log, and allergic to any. I thought TypeScript was just unnecessary ceremony. I told myself I was moving faster by skipping types. Then I built something that mattered. It started with a side project that slowly turned into a real product—users, edge cases, customer feedback, weird data coming from APIs I didn’t fully control. The codebase ballooned. Adding a single new feature felt like playing Jenga with a blindfold. I dreaded refactoring. And the bugs... they weren’t even clever. Just dumb little things that static types would’ve caught in seconds. So I gave in. I installed TypeScript. At first, it was annoying. I’ll be honest. Type errors…  ( 4 min )

We’ve all seen the hype: AI tools like GitHub Copilot, ChatGPT, Google Gemini Code Assist, Meta Code Llama, and Replit AI promise to turn anyone into a 10x developer overnight. But if you’ve actually tried building something original—especially as a beginner—you know the truth: 👉 AI-generated code often falls short, and relying on it blindly can lead to frustration. The Hard Truth About AI Coding Assistants 1️⃣ They Struggle with Unique Projects A 2024 Stanford study found that while AI can help with boilerplate code, it still struggles with complex, novel tasks. If your project isn’t a clone of existing tutorials, expect to debug more than you generate. 2️⃣ Debugging Isn’t Automated (Yet) According to the 2024 Stack Overflow Developer Survey, 79% of developers still manually debug AI-generated code—showing some progress, but manual debugging remains the norm. 3️⃣ You Still Need Fundamentals Even Google’s AI lead, Jeff Dean, admits: “AI can help write code, but it can’t replace understanding how code works.” If you don’t know why something fails, you’re stuck. So, Should You Use AI for Coding? ✅ Yes, as a helper—for repetitive tasks, syntax suggestions, or learning. ❌ No, as a replacement—because when the AI gets confused (and it will), you need to step in. The Bottom Line AI is a powerful tool, but real coding skill comes from practice, problem-solving, and patience. The sooner you embrace the grind, the better developer you’ll become.

TL;DR: Pandemic Studios actually kicked off Star Wars Battlefront 3 right after Battlefront II, dreaming up cool next-gen features like seamless space-to-ground combat. But LucasArts insisted on a one-year turnaround to hit marketing beats for Episode III—and with new PS3/Xbox 360 hardware in play, Pandemic couldn’t nail down the tech fast enough. Negotiations stalled, the project died, and LucasArts handed development (and eventual cancellation) over to Free Radical Design. In the end Pandemic folded in 2009, BF3 never saw the light of day, and EA’s rebooted Battlefront II (2017) remains the closest thing fans have to a sequel.  ( 3 min )

A former Battlefront 2 dev, Mats Helge Holm, says he and “many” of his ex-DICE colleagues would love to “get the gang back together” to build Star Wars Battlefront 3—especially after a surprise resurgence of interest on Reddit and TikTok. Despite EA ending support for the 2017 game in 2020, fans have flocked back and reignited hopes for a proper follow-up. Battlefront 2 famously stumbled at launch thanks to aggressive microtransactions (you needed around 40 hours of playtime just to unlock one hero), but EA pulled the loot crates after a massive backlash—reportedly even Disney got involved. The overhaul paid off: the game now enjoys a passionate community, gorgeous visuals, smooth gameplay and all its best heroes available for free.  ( 3 min )

Games Workshop is riding a major Warhammer high, handing out £20 million (about $27 million) in bonuses to its roughly 1,500 staff (around £13,300 each) after another blockbuster year.

While the company’s bread-and-butter remains its iconic tabletop miniatures, it’s increasingly cashing in on IP—video games like Space Marine 2 (and a Space Marine 3 in the works), Amazon’s Secret Level animation, and a Henry Cavill–fronted Warhammer 40K cinematic universe deal. Licensing hit record highs this year (though it may ease off next), but with fresh Warhammer Skulls announcements (hello, Dawn of War Definitive Edition and Space Marine 2’s Siege Mode), the 40K juggernaut shows no signs of slowing.  ( 3 min )

Let's crack open that EF Core mystery: Why does AddAsync() exist when there's no UpdateAsync() or RemoveAsync()? Feels like unfair treatment, right? Spoiler: It’s not favoritism—it’s about async value generation, not database calls. Let’s break it down. AddAsync() does NOT talk to your database. Nope, not even a little. When you write: await db.Users.AddAsync(user); Zero bytes hit the database. All it does is tell EF: "Track this new entity; insert it later when I save." The actual INSERT happens at SaveChangesAsync(). So why Async? 🤔 Imagine your entity needs a unique ID before saving, like a distributed Snowflake ID from an external service: public class Order { public long Id { get; set; } // Generated by a fancy async service! public string Customer { get; set; } } You…  ( 4 min )

Fortnite has finally busted back onto the iOS App Store after a five-year ban, thanks to a court order from Judge Yvonne Gonzalez Rogers forcing Apple to reinstate the game—or prove a legal reason not to. Epic had submitted Fortnite for review only to be stonewalled by Apple until the judge stepped in; within 24 hours of her ruling, the battle royale was back on iPhones. Epic didn’t go it alone, though. Microsoft filed an amicus brief backing Epic (it’s itching to launch an Xbox mobile store and hates Apple’s in-app purchase rules), and Spotify, Meta and X chimed in too—Spotify even became the first big name to roll out external payment links once Apple was compelled to allow them. All that courtroom tag-teaming means the saga is winding down, and U.S. players can jump into Fortnite on iOS again.  ( 3 min )

TL;DR: After riding high on the success of Star Wars Battlefront I & II, Pandemic Studios quietly kicked off a third instalment—only to have LucasArts demand another one-year turnaround on next-gen consoles (PS3/Xbox 360). Pandemic barely got off the ground before negotiations stalled; shifting hardware, unknown dev tools and tight marketing beats meant they simply couldn’t hit Lucasfilm’s timeline. Rumours of epic space-to-ground battles (think seamless dogfights that drop you onto the battlefield) never made it past tech demos. Free Radical Design later picked up the baton and reached 95% completion, but that version was also canned. As Pandemic’s doors closed in 2009, it became clear: a true Battlefront III was never meant to be—at least not on anyone’s schedule.  ( 3 min )

Hey everyone 👋 I’m a 2023 Computer Science graduate. I started off as a backend developer at a startup, but due to financial needs, I later took up a non-tech role at Amazon. Tried switching internally — didn’t work out. Like many, I turned to DSA prep to get back into tech, but it’s super competitive out there. Recently, I discovered Salesforce and it really caught my interest. It’s technical, structured, and I like that it’s tied to solving real business problems. The only concern? I’ve been hearing that Salesforce roles are becoming saturated, especially for freshers or newcomers trying to break in. I genuinely love working with technology, regardless of the platform. Just trying to figure out if Salesforce is a smart move at this point or if I should continue focusing on traditional dev paths. If you’ve made the switch or know someone who did, I’d really appreciate your thoughts! Thanks in advance! 🙏  ( 3 min )

In JavaScript, event handling functions like click and others are commonly used to interact with HTML elements. Here's a breakdown of the .click() function and other similar event-related functions: .click() Function The .click() method programmatically triggers a click event on an element. document.getElementById("myButton").click(); // Simulates a click But normally, we use .addEventListener() or onclick to respond to a real user click. Click Me document.getElementById("myButton").addEventListener("click", function () { alert("Button clicked!"); }); Common Event Listener Functions You can handle many types of events using .addEventListener(): Event Type Description click Fires when an element is clicked dblclick Fires on double-click mouseover Fires when the mouse is over an element mouseout Fires when the mouse leaves an element mousedown Fires when mouse button is pressed mouseup Fires when mouse button is released mousemove Fires when the mouse moves keydown Fires when a keyboard key is pressed keyup Fires when a keyboard key is released input Fires when the value of changes change Fires when input or select changes submit Fires when a form is submitted load Fires when the page or image is fully loaded scroll Fires when an element is scrolled Basic Example document.getElementById("nameInput").addEventListener("input", function (event) { document.getElementById("output").textContent = "You typed: " + event.target.value; }); Shorthand onclick Method Instead of .addEventListener, you can also directly assign a function: document.getElementById("myButton").onclick = function () { alert("Clicked via onclick"); };  ( 3 min )

Great! You're learning JavaScript, especially about local variables and the DOM (Document Object Model)—those are essential concepts in web development. Here's a simple blog-style explanation to help reinforce your learning: In JavaScript, a local variable is a variable that is declared inside a function or block, and it can only be used within that function or block. function greet() { let message = "Hello, world!"; console.log(message); } greet(); // Outputs: Hello, world! console.log(message); // ❌ Error! 'message' is not defined outside the function let message = "Hello, world!" is a local variable, so you cannot use it outside the greet() function. DOM stands for Document Object Model. It represents the structure of a web page as a tree of objects in JavaScript. With the DOM, you can: Read or change content Change styles (CSS) Add or remove HTML elements Original Text Click Me function changeText() { let element = document.getElementById("demo"); element.innerHTML = "Text has been changed!"; } When the button is clicked: JavaScript finds the tag with id="demo" Changes its content to "Text has been changed!" 🛠️ Why It Matters Local variables help avoid bugs by keeping variables where they belong. The DOM lets you make web pages interactive—like showing messages, changing colors, or responding to clicks. Would you like a small project to practice with these concepts?  ( 3 min )

🚀 What if building a 🐍 Snake game was as easy as typing a sentence into your terminal? That’s exactly what I did with Amazon Q Developer CLI — and it completely changed how I approach side projects 🤯. I created a colorful, classic Snake game in Python with a grid-based layout, food generation, a snake that changes colors every few seconds, score tracking, and a game-over screen with a restart option. All of it was generated and iterated on using nothing but conversational prompts. Here’s how I did it. To get started, I first installed WSL on my Windows machine and set up Ubuntu: wsl --install -d Ubuntu wsl -d Ubuntu sudo apt install unzip curl --proto '=https' --tlsv1.2 -sSf https://desktop-release.codewhisperer.us-east-1.amazonaws.com/latest/q-x86_64-linux-musl.zip -o q.zip   q login "Create a classic colorful snake game in Python using pygame. The game should have a grid, food, colorful snake, score, and end screen." "Make the snake colorful with changing colors every few seconds." https://github.com/akanksha3012/snake_game_QCLI) Faster prototyping. Clear, readable code. Built-in error resolution. And best of all — no constant context-switching or documentation rabbit holes. Just a focused, fluid development experience. It made me think: 1. What else could I build this way?   Amazon Q CLI isn’t just a tool — it’s a shift in how we can bring ideas to life faster and smarter.   Have you tried it yet?

🔹 What is a Local Variable in JavaScript? A local variable is one that is declared inside a function or block and is only accessible within that function or block. You can declare a local variable using let, const, or var inside a function or block: let or const (block-scoped, preferred): ```java script example(); console.log(local Variable); // ❌ Error: local Variable is not defined #### Using `var` (function-scoped): ```java script function example Var() { var local Var = 'I am local'; console.log(local Var); // I am local } example Var(); console.log(local Var); // ❌ Error: local Var is not defined let vs var let and const have block scope. var has function scope (not block-level), so it behaves differently in loops or conditionals. ```java script console.log(bl…  ( 4 min )

AI agents As a software developer, I create scripts and applications to automate the tedious parts of my job - and my life. Rather than tools in a tool belt, I have always thought of these apps as a menagerie of creatures. Each has its own abilities. To solve a problem, I can simply select one and unleash it on the world, where it can run along and do my bidding. In our modern world of AI agents, this fantasy of mine has grown more real. AI is now at the point where these little minions can each be imbued with their own intelligence. Any one of us can have our own digital workforce acting on our behalf. Any one can control their own menagerie of AI agents. At work, we create agents using frameworks like LangGraph.

Instead of: 💬 "We need to refactor this technical debt." Try this: 💡 "This takes 3 extra days now but saves 2 days on every future feature. We break even after the second feature." Initial Investment ÷ Time Saved per Cycle = Break-even Point For example: "This refactor takes 3 extra days now, but it saves 2 days on every future feature. That means we break even after feature two—and save time from then on."* Product managers think in timelines and ROI, not architecture. Give them numbers they can actually use to make business decisions. In your next planning meeting, translate one technical decision into time/cost terms instead of just calling it “debt.” It shifts the conversation from “please trust us” to “here’s the business case.” 👉 What's your go-to phrase for explaining tech tradeoffs to non-devs?  ( 3 min )

Written by Temitope Oyedele✏️ Next.js middleware lets you run code before a request finishes and update the response. Alongside Edge Functions, it's a powerful tool that enables developers to achieve enhanced functionality and performance. Middleware was introduced in Next.js v12 and has been improved in consecutive versions. Starting with Next.js v13, middleware can be used to respond directly to requests without going through the route handler. This can improve performance and security. Middleware can also be used to work with Vercel Edge Functions. Edge Functions allow you to run code at the network's edge. So, in this post, we’ll learn how middleware works with Edge Functions and why it’s important to know. Now, let’s get started! Middleware in Next.js is a piece of code that allows y…  ( 12 min )

Hi Dev Community! 👋 My name is El Bachir (Elox), and I’m based in Senegal. I’m currently leading Santel Healthcare, an early-stage project aiming to transform healthcare access across Africa through digital innovation, community-led savings, and systemic reform. We believe that tech can be a bridge — not just a tool — in addressing deep-rooted challenges in health systems. Santel is designed to be more than an app: it’s a movement combining technology, policy advocacy, and inclusive models of care. 🚀 What we’re building: A first digital prototype (web/mobile) that helps: We’re currently a small team: ⸻ 👩‍💻 Who we’re looking for: A volunteer developer (frontend or fullstack) who: 💡 We’re also open to evolving the role into a long-term collaboration — potentially even a cofounder position — if there’s shared vision and alignment. ⸻ 🧭 Why this matters: In many African countries, people are one illness away from financial catastrophe. Health access is unequal, data is fragmented, and community potential is underused. We believe we can build something simple but powerful to help shift that — together. ⸻ 📩 Interested?

To simplify this process, we’ve developed a visual tool—BLE Star Topology Visualizer—that connects to a BleuIO USB dongle and graphically maps nearby advertising BLE devices using RSSI-based distance estimation. This project not only provides a live BLE scan but also visualizes the proximity of devices in a central-node star topology. The BLE Star Topology Visualizer is a web-based application that: Connects to a BleuIO USB dongle via Web Serial API. Performs a BLE GAP scan using AT+GAPSCAN=x to detect nearby BLE devices. Displays detected devices as nodes around the central BleuIO dongle. Uses RSSI (Received Sign…  ( 4 min )

AI platforms are great at building functional apps quickly, but they often skip basic security measures. Here are five copy-paste prompts that will add essential security to any AI-generated application. The Problem: AI platforms rarely validate user input properly, leaving your app vulnerable to injection attacks. Copy this prompt: Add input validation to all forms that: - Removes HTML tags and script elements from text inputs - Validates email formats before saving - Limits text input length to reasonable maximums - Escapes special characters in database queries - Shows specific error messages for invalid input What this prevents: XSS attacks, SQL injection, and data corruption from malicious or malformed input. The Problem: Basic login/logout isn't enough. Most AI apps have weak sessio…  ( 5 min )

JavaScript is one of the most popular and powerful programming languages used to create interactive websites and web applications. Types of JavaScript Variables Functions Concatenation Return statements Calling Functions 🧩 1. Types in JavaScript JavaScript supports several data types, which can be grouped into two categories: These are the basic types: String: Text. Example: "Hello" Number: Numeric values. Example: 42, 3.14 Boolean: true or false Null: A deliberate non-value Undefined: A variable that has been declared but not assigned Symbol: Unique values (advanced) BigInt: Large integers (new in ES2020) let name = "Sivasankari"; // String 🔸 Non-Primitive Types Object Array Function let person = { name: "Sivasankari", age: 23 }; // Object 🧪 2. Variables in JavaScript Variables store data values. In modern JavaScript, we use: let: Block-scoped variable (preferred) const: Block-scoped, constant value var: Function-scoped (older and less recommended) let city = "Coimbatore"; 🔧 3. Functions in JavaScript Functions are reusable blocks of code that perform a task. Here's how to declare and use them: function greet() { greet(); // Call the function Parameters and Arguments function greetUser(name) { greetUser("Alice"); // Output: Hello, Alice! 🔗 4. Concatenation in JavaScript Concatenation means combining strings. let firstName = "Siva"; 🎁 5. Return Statement The return keyword gives back a result from a function. function add(a, b) { let sum = add(10, 5); // sum is 15 If you don't use return, the function will return undefined by default. 📞 6. Calling Functions Once a function is defined, you can call or invoke it by using its name followed by parentheses (). function sayHello() { sayHello(); // Output: Hello! 🏁 Conclusion JavaScript is a powerful language, but understanding these fundamentals — types, variables, functions, return statements, concatenation, and function calls — is a solid first step.  ( 3 min )

Hey devs! 👋 Alpha Bomb — a fast-paced typing defense game built in Godot. If you like games that test your reflexes and improve your typing, you’ll enjoy this one. 😄 🎮 What Is Alpha Bomb? Imagine this: You're defending a city from falling bombs. Each bomb has a single alphabet letter. To destroy the bomb? Type that letter before it hits the ground. If you miss too many, your city starts to crumble... It’s simple, addictive, and fun — with a retro vibe and an educational twist. 🔗 Play Now: https://playhvn.itch.io/alpha-bomb By Studio: PlayHvn 🛠️ How I Built It (Using Godot!) As a huge fan of open-source engines, I chose Godot for this project — and it was a blast! Here are some behind-the-scenes highlights: 💡 Typing Mechanics Using InputEventKey in Godot, I mapped each falling bomb’s letter to real-time keyboard inputs. This gave the game a responsive and satisfying feel — every keystroke is a mini victory. 🎯 Collision & Timing Each bomb is a node that tracks its vertical movement. If it reaches the bottom and hasn't been typed, the game deducts health from the city. Managing performance with dozens of bombs onscreen taught me a lot about optimization and pooling. 🔊 Sound & Feedback I used subtle sound cues and explosions to reward correct typing, and dramatic screen shakes when the city takes damage. Feedback = immersion. 💥 Why I Made This Game I wanted to: Practice real-time input handling Build something fast and replayable Create a game that’s fun but also boosts typing skills 💬 What I’d Love From You If you play the game, I’d genuinely appreciate: ✅ Feedback on difficulty, pacing, or ideas 🙌 Let’s Connect Made by PlayHvn 👉 Try It Now: https://playhvn.itch.io/alpha-bomb Thanks for reading, and let me know what you are building in Godot! 🚀  ( 3 min )

Large language models are used widely across the industry these days. Yet still, many people are skeptical about their capabilities as they are quite prone to hallucination. For that reason, in this article, I decided to use LLM in a case where there are no incorrect answers: generating artistic text. However, even in the case of art which is highly subjective, there are still some quality gates (or shall I say personal preferences?). So how do I trick a model into generating text that suits my artistic taste? While prompt engineering can get you this far, I decided to provide LLM with data that would represent my view of fine art.

From Vec to Slice: Writing Generic Functions over Collections When writing Rust code, one of the most important lessons to learn is how to make your functions flexible and reusable. A common mistake among Rust newcomers (and even seasoned developers) is writing functions that are overly specific—for instance, functions that accept a Vec when they could work just as well with a &[T]. This subtle but powerful change can make your code more versatile and easier to use. In this blog post, we’ll explore why writing functions over slices is often preferable to writing functions over concrete collections like Vec. You’ll learn how to replace &Vec with &[T], the advantages of this approach, and how to avoid common pitfalls. Whether you’re tackling algorithm implementations or designing API…  ( 5 min )

Too many founders jump into building their MVP with excitement—and end up rebuilding it again, just a few weeks later. Why? Because they started coding (or no-coding) before scoping. At Prime Dev, I help founders avoid that mistake by doing one thing first: 👉 We define what matters before we build anything. Instead of asking “What’s the one thing our app must do on day one?”, founders often ask: “What features should we add?” “Can we build a dashboard?” “What if users want X too?” This leads to bloated MVPs, longer timelines, and wasted budget. Before you touch Glide, Webflow, or custom code—ask: Who is using this? What exactly do they want to achieve? What’s the one action they need to do successfully? What’s absolutely critical for them to get value? From there, your MVP is obvious. A founder I worked with wanted to build a full platform for tracking expenses via banking APIs. We scoped it down to a simple budgeting app that accepts uploaded CSVs first, saving 6+ weeks of development and letting users onboard faster. The feedback? “This is exactly what I needed. I would have never used the full version yet.” [ ] Who is the one user we’re targeting? [ ] What is the one action that gives them value? [ ] What is the smallest feature set that makes that action possible? [ ] What can wait for version 2? If you can check those four, you’re ready to build. I specialize in no-code MVPs using Glide and Webflow. But before we build, I help you scope your MVP like a product manager—not just a developer. From idea to launch in weeks Based on what users actually need Built lean, tested early I help founders scope and build no-code MVPs with speed and clarity. 👉 Book a free MVP strategy call: https://calendly.com/samir-prime-dev/30min 💬 Connect on LinkedIn: linkedin.com/in/samir-adel 🐦 DM me on X: x.com/samircs Let’s save your time, budget, and momentum before you waste it.  ( 3 min )

In today’s web, real-time features like live chat, notifications, and multiplayer games are everywhere. But how do these apps update instantly — without needing to refresh the page?

The Sad Reality Behind @Threads: Fake Users and Fading Popularity Meta, the social media giant behind Facebook and Instagram, has a long history of leveraging its existing platforms to push new apps. Threads was no different. By auto-connecting Instagram followers, it gave the impression of an instant, bustling community. However, much of this community turned out to be artificial — accounts created en masse, often bots or ghost profiles designed to inflate user metrics. This tactic, while perhaps effective at first glance, undermines the very essence of social media: authentic, meaningful interactions. Why do fake users matter so much? Because they distort the ecosystem. When an app’s “user base” is bloated with bots, the number of real conversations shrinks. Genuine users find fewer real…  ( 4 min )

Imagine your application isn't just one piece of software, but a team of services – like a web frontend, a database, and a backend API. Each of these might need its own Docker container. This is where Docker Compose comes in. It's a tool for defining and running multi-container Docker applications. Instead of manually starting each container with complex docker run commands and linking them, you describe your entire application stack in a single docker-compose.yml file. Think of Docker Compose as the conductor of your container orchestra. You define your services (like the web app, database, and message queue), their configurations, how they connect, and their dependencies in this YAML file. Then, with a single command (docker compose up), Docker Compose reads this file and spins up, conne…  ( 4 min )

Structure is more than just file organization in any expanding React application; it's about building a scalable, maintainable framework on which developers may build. Bad architectural choices can result in needless complexity, repeated code, and longer development cycles as teams grow and codebases change. Even basic functionality may become challenging to build, debug, or test in the absence of a defined structure. Early implementation of a strong design helps avoid these problems and positions your project for long-term success. It is important to lay a strong foundation with appropriate tooling and environment settings before developing any application code. Repetitive checks are automated and mistakes are avoided early by setting up tools like Husky for git hooks, Prettier for unifo…  ( 7 min )

When you build a website, you have to choose how pages are displayed to users. For this many people turn to two different paths and those are Client-side Rendering (CSR) and Server-side Rendering (SSR). They can improve your site’s loading time and affect how Google and similar search engines see your site and how people use the website. Next.JS which is a popular React framework, makes things simpler to use any of these. These concepts are explained clearly in this blog, along with a brief FAQ sections to clear up doubts that many of you might have. Rendering is similar to showing your code as a picture that appears on users’ screens. It can occur in two different locations. Server: A machine in another location that makes the page for you. Client: The browser such as Chrome or Firefox, …  ( 5 min )

Your AI agent works perfectly in development. You've tested the reasoning chains, the tool integrations are solid, and the responses are exactly what users need. Then you deploy to production and everything breaks. The timeout kills your multi-step workflows after 15 minutes. Your bundle exceeds the 250MB limit because you need scikit-learn, pandas, and a vector database client. Cold starts take 6+ seconds while your models load, making real-time interactions impossible. Sound familiar? You're not alone. One developer working on an e-commerce recommendation engine discovered that "scikit-learn and pandas libraries increased the size of my deployment package beyond the AWS Lambda package limits." Another found their TensorFlow model loading caused API calls to timeout after 29 seconds. Here…  ( 8 min )

You're not Beyoncé, but you should treat your talk deserves a tour I’m a Beyoncé fan. I’m not going to argue with you online, but I’m going to every concert. When I was younger, my sisters and I would dance to “Ego” while my mom was out grocery shopping. The second we heard the door open, we’d scramble to turn off on-demand music videos on TV and pretend we were studying. (My middle sister now claims she never wanted to dance with us, but I'm a bossy big sister, so she had no choice). My husband is also a huge Beyoncé fan. Since we’ve had enough money and a license, he’s brought me to all of her concerts. I’m currently reading Matriarch, her mom’s memoir. Beyoncé is a source of inspiration.

Another Wednesday, another mini-tutorial! Today, we’re doing something super practical: adding a QR code to your website. Because sometimes, sharing a link the old-school way just doesn’t cut it. Quick answer: they’re easy, mobile-friendly and just cool. QR codes let users scan and go; they could scan a contact form, app download or your portfolio link, Scan Me! That’s your placeholder. Now let’s generate the actual QR code. We’ll use a popular lightweight library called QRCode.js. You can include it via CDN: Now generate the QR code and target the #qrcode div: const qrcode = new QRCode(document.getElementById("qrcode"), { text: "https://your-link-here.com", width: 128, height: 128, colorDark: "#000000", colorLight: "#ffffff", correctLevel: QRCode.CorrectLevel.H }); Replace the text value with the link you want users to scan. Here’s a little CSS to centre the QR code and keep things neat: body { font-family: sans-serif; background-color: #f4f4f4; color: #333; display: flex; justify-content: center; align-items: center; } .card { background: #ffffff; border-radius: 10px; box-shadow: 0 4px 12px rgba(0, 0, 0, 0.1); padding: 2rem; width: 300px; display: flex; flex-direction: column; justify-content: center; align-items: center; } #qrcode { margin-top: 1rem; } Feel free to customise it, round corners, borders, drop shadows, etc... You now have a working QR code on your site! Check it out in this Codepen Let users generate QR codes dynamically by typing a URL and clicking a button. Wanna see that next Wednesday? Let me know!

Your servers are spiking and you need to be able to cope without breaking the bank. Let’s move you to the cloud, where you can deal with your new demand with cost-effective ease. A Virtual Private Cloud (VPC) is essentially your own private network slice within the cloud, fully isolated from other tenants. Inside a VPC, you get to define your IP address ranges, create public and private subnets, and set up route tables and internet or virtual private gateways to control traffic flows. Setting up is important. Instead of hosting your servers in a flat network, it’s best to have a VPC (Virtual Private Cloud). This will create a secure environment where it’s much easier to get your servers talking to each other without being at risk of lateral attacks. First, select the VPC tab under Networki…  ( 5 min )

Hello Devs! ✌️ In today’s session, we’re diving deeper into JavaScript fundamentals. If you’re just getting started, this will help set a solid base. Let’s break it down simply. 📌 Datatypes: JavaScript has different types of data you can work with. The most common are: • String→ text → "Hello World" Number → numbers → 42, 3.14 Boolean → true/false → true, false Undefined→ no value assigned Null → intentionally empty Object → key-value pairs → {name: "Alex"} Array→ list of items → [1, 2, 3] ⮞ Example: let name = "Alex"; // string let age = 25; // number let isStudent = true; // boolean 📌 Variables: We store data in variables. In modern JS, we mostly use: •let → value can change const→ value cannot change (constant) ⮞ Example: let city = "New York"; city = "London"; // this works const country = "USA"; // country = "Canada"; // ❌ error 📌 Functions A function is a reusable block of code that performs a task. ⮞ Example: function greet() { console.log("Hello!"); } We call or invoke a function like this: greet(); // Output: Hello! 📌 Return & Arguments Functions can take arguments (inputs) and return outputs. ⮞ Example: function add(a, b) { return a + b; } let sum = add(5, 3); // sum = 8 console.log(sum); // Output: 8 📌 String Concatenation We combine (concatenate) strings using +. ⮞ Example: let firstName = "Alex"; let lastName = "Smith"; let fullName = firstName + " " + lastName; console.log(fullName); // Output: Alex Smith 🚀Quick Recap ✔ Datatypes help define the kind of data. Variablesstore data. Functions let us organize reusable logic. Arguments & returnallow input and output. Concatenation connects strings. That’s a wrap for Session 2! Thanks for reading — happy coding! ✨  ( 3 min )

Java is a statically typed, object-oriented programming language for building platform-independent applications. JavaScript is a dynamically typed scripting language primarily used for interactive web development. Despite similar names, they serve different purposes and have distinct syntax, runtime environments, and use cases. JavaScript was created in the first place for DOM manipulation. Earlier websites were mostly static, after JS was created dynamic Web sites were made. Functions in JS are objects. They may have properties and methods just like other objects. They can be passed as arguments in other functions. Can handle date and time. Performs Form Validation although the forms are created using HTML. No compiler is needed.

I use Google Maps a lot to find local shops and services — cafés, tattoo artists, yoga studios. But too often, their links lead to Instagram or Facebook pages, where I have to accept cookies, dodge login popups, or scroll past ads just to access basic info like opening hours or a portfolio. It’s frustrating. This kind of information should be public by default — not locked behind Meta’s walls. This Isn’t What the Web Was Meant For. Small businesses deserve better than to have their storefronts locked behind walled gardens. And people deserve access to that info without handing over their data to Meta. They should publish it on a bluesky account instead! I’m working on hopefully.blue — a new tool that gives small businesses a clean, Bluesky-powered profile page. Think Linktree meets Micro.blog, but for Bluesky. Your business posts to Bluesky. We generate a public-facing profile that lives outside Meta/ X (any other big corp). No login needed. No cookies. Just your info, presented beautifully. Your bio and pinned post become your “About” section. Your latest photos show up on the side as an image wall. It's free It’s fast, privacy-friendly, and 100% public.

Back when I was studying at the College of Engineering, Trivandrum (Any CETians here?), during my MCA days, we had tons of fun in our hostel rooms. Only one of us had a UPS for his computer, so whenever there was a power cut, we all gathered in his room. His screen was the only one lit up, and we’d play a Flash game called Hangaroo—a Hangman clone where you had to guess the word before the kangaroo met its fate! Those memories still bring a smile to my face. When I came to know about the Q CLI Game Challenge, I immediately knew what I was going to build - a recreation of dear old Hangaroo!

When you run a lot of Docker containers, it can be hard to see what is going on. Each container writes logs and these logs might be important. They help you know if something is broken. They also help you understand how your app is working. But logs from many containers on many servers? That can get messy. This is why people use centralized logging. Centralized logging means all logs go to one place so that you can look at them easily. In this post, we will talk about how to collect logs from Docker. We will see what tools people use. And we will look at the pros and cons of each. Logs are like notes that your app writes. These notes say what the app is doing. If the app crashes, the logs can tell you why. If users have problems, the logs help you understand them. Without logs, fixing bugs…  ( 5 min )

If you're working with maps, geometry, or location-based data, PostGIS is an essential tool. In this article, we’ll explore what a polygon is in PostGIS, what the parameters in a polygon definition mean, and the role of ST_ functions in spatial queries. A polygon in PostGIS is a two-dimensional geometric object that represents an enclosed area defined by one or more rings: The outer ring defines the exterior boundary. Inner rings (optional) define holes within the polygon. Each ring is made up of at least four coordinate points, and the first and last point must be the same to form a closed loop. Consider the following SQL query: SELECT ST_GeomFromText('POLYGON((0 0, 0…  ( 4 min )

The Australian Army is currently trialling an advanced artificial intelligence (AI) system named TrapRadio, designed to generate deceptive radio communications to mislead adversaries and enhance frontline protection. Developed by British-Australian company Penten Amio, TrapRadio employs AI to create synthetic radio traffic that mimics high-value communications or transmission patterns, effectively diverting enemy attention and resources away from actual operations. This technology mirrors cybersecurity strategies where decoy systems and data are used to distract threat actors. TrapRadio was recently tested during a large-scale international military exercise in California, involving 140 Australian Defence Force personnel. The system demonstrated its capability to support soldiers through force protection and by creating dilemmas for adversaries via AI-generated deceptions. Captain Wayne Mulhall from the Electronic Warfare division at Army Headquarters highlighted TrapRadio's potential to reshape the battlefield by mimicking high-value targets, thereby creating strategic dilemmas for enemy operators. This initiative underscores the Australian Defence Force's commitment to integrating cutting-edge AI technologies to enhance operational effectiveness and soldier safety.

I Tried to Escape Blockchain—Then It Saved My Business, My Dog, and My Sanity (Kind Of) Hey there, internet traveler If you're here, chances are you're either terrified of blockchain, sick of hearing about it, or secretly intrigued but pretending not to care because crypto bros ruined your LinkedIn feed in 2021. I get it. Five years ago, I thought “blockchain” was just what happened when your toilet chain got tangled. I rolled my eyes at every buzzword: NFTs, smart contracts, decentralization. Sounded like stuff tech bros yelled about over overpriced oat milk lattes. But then I saw the light—or rather, I saw my first smart contract in action.

JavaScript is one of the most widely-used programming languages for web development. Whether you're just getting started or brushing up on the basics, understanding how variables work and how to connect your code to HTML is essential. In this post, we’ll explore: What are global and local variables? How to link JavaScript in an HTML file. Before you can run JavaScript, you need to link it to your HTML file. There are two common ways to do this: 1. Inline JavaScript(not recommended for large projects) 2. External JavaScript File (best practice) Create a file named script.js: // script.js Link it in your HTML file: ✅ Tip: Global Variable A global variable is declared outside of any function. It can be accessed and modified anywhere in the code. let globalMessage = "I'm a global variable!"; function showMessage() { Local Variable A local variable is declared inside a function. It can only be accessed within that function. function showLocalMessage() { ⚠️ Remember: The DOM is a programming interface for HTML and XML documents. It represents the page so that programs (like JavaScript) can change the document structure, style, and content. Example: HTML: Hello! JavaScript: function changeText() { } When the button is clicked, the text will change — thanks to JavaScript and the DOM. Topic Key Point Global Variable Declared outside functions; accessible everywhere Local Variable Declared inside functions; limited scope Linking JS Use tag with src or inline DOM Lets JavaScript interact with HTML elements  ( 3 min )

Hi, I’m rhara, a software engineer at Axelspace. In this post, I’ll share how we reduced the size of an InfluxDB OSS v1 EBS volume from 5.9TiB to 2.9TiB by removing duplicate data. Since I couldn’t find much information on this process, I’m writing this as both a record and a reference. Note: This method requires creating a new InfluxDB database with a different name, meaning the original database name cannot be retained. To restore the original name, additional steps such as using the SELECT * INTO clause again are required. InfluxDB is a time-series database optimized for storing and querying time-based data, especially in use cases where high write and read throughput is important—such as log aggregation. (Docs) At Axelspace, we use InfluxDB to store satellite telemetry data, such as p…  ( 5 min )

The definition of association in SQL is overly simplistic: association is essentially performing a Cartesian product of two tables and then filtering the result, expressed in syntax like A JOIN B ON .... Python’s approach to association largely follows the SQL approach, with similar concepts and methods. However, esProc SPL understands association differently, with a definition that is no longer related to the Cartesian product. SPL divides association into two categories. One is called foreign key association, which refers to the association between a regular field (foreign key) of one table and the primary key of the other. For example, the foreign keys employee_id and customer_id of the orders table are associated with the primary keys of the customers and employees tables, respectively…  ( 8 min )

The Shadow DOM is like the secret room in a house — it’s hidden, self-contained, and not everyone knows how to use it. On one hand, it’s a magical tool for building components that are encapsulated from the rest of your app. On the other hand, it can make you question your life choices when things go wrong. Let’s break it down, shall we? What is the Shadow DOM The Shadow DOM is a part of the Web Components spec that lets you create encapsulated DOM for your elements. Essentially, you can create a "mini DOM" inside a parent element, and it won’t mess with the global styles or scripts. For example: Hello, World! , you can create a Shadow DOM like so: class CustomElement extends HTMLElement { constructor() { …  ( 5 min )

__ _1️⃣ Data Types in JavaScript JavaScript has several built-in data types. These are categorized into primitive and non-primitive (object) types. String – Text data let name = "Alice"; Number – Integer or floating-point numbers let age = 25; Boolean – true or false let isStudent = true; Undefined – A variable that has been declared but not assigned a value let x; Null – Represents an intentional absence of value let data = null; Symbol – Unique and immutable primitive value BigInt – For large integers 🔸 Non-Primitive (Objects, Arrays, Functions) let person = { name: "Bob", age: 30 }; *2️⃣ Variables: var, let, and const JavaScript uses keywords to declare variables: var – Function-scoped (older way) let – Block-scoped, can be reassigned const – Block-scoped, cannot be reassigned let city = "New York"; 3️⃣ Functions in JavaScript Functions are reusable blocks of code that perform specific tasks. function greet() { 🧪 Calling a Function greet(); // Output: Hello, world! *4️⃣ Function Arguments You can pass values to functions using arguments. function greetUser(name) { greetUser("Alice"); // Output: Hello, Alice! 5️⃣ Return Values Functions can return values using the return keyword. function add(a, b) { let sum = add(5, 10); ✅ Conclusion JavaScript becomes powerful once you understand its core components: Data types help store different kinds of information Variables let you store and reuse that data Functions allow you to organize and execute logic in a clean way In the next post, we’ll explore control flow with if, else, loops, and more!  ( 3 min )

📌 1. Global Variables A global variable is declared outside of any function and can be accessed from anywhere in the code (inside or outside functions). Example: let globalVar = "I am global"; function showGlobal() { console.log(globalVar); // Can access globalVar } showGlobal(); console.log(globalVar); // Also accessible here 2. Local Variables A local variable is declared inside a function (or block using let/const) and can only be accessed within that function or block. Example: function showLocal() { let localVar = "I am local"; console.log(localVar); // OK } showLocal(); // console.log(localVar); // ❌ Error: localVar is not defined Block Scope with let and const Variables declared with let or const are block-scoped, which means they're only accessible within { } braces. if (true) { let blockVar = "Inside block"; console.log(blockVar); // OK } // console.log(blockVar); // ❌ Error Note on var var is function-scoped but not block-scoped. function testVar() { if (true) { var x = 10; } console.log(x); // ✅ Works: x is function-scoped } testVar(); Comparison Table Type Scope Accessible From Keyword Global Entire script Anywhere var, let, const (outside) Local Function/Block Only inside its block let, const, var (inside) Global Variable = Accessible anywhere in the file.

When working toward PCI-DSS compliance in containerized environments, one of the most critical components to get right is the container image itself. Docker images form the foundation of your deployed applications, and any misconfiguration, vulnerability, or bloat at this level can have cascading effects on your security posture. PCI-DSS emphasizes minimizing the attack surface, enforcing least privilege, and maintaining traceable controls - all of which can (and should) be implemented directly during image creation. Start by choosing your base image carefully. Bloated, outdated images not only increase the size of your containers but also multiply the number of possible vulnerabilities. Use minimal, purpose-built base images like Alpine or Distroless whenever possible. These images contai…  ( 5 min )

Good morning, everyone. Today's topic is about the life cycle in Cangjie's language development. In fact, You LAN Jun prefers to share practical code writing and doesn't like to talk too much about theoretical things. The reason why I wrote a separate article today to share the content of the life cycle is that if this part is not covered, it's really easy to fall into a trap. The life cycle refers to the process from loading, displaying to disappearing of a page or component. During this process, there will be some system events, and we can perform some operations in it. For instance, in ArkTs, there are methods such as aboutToAppear() and onPageShow(). So, what is the life cycle like in Cangjie?

This is one of the most powerful habits I wish remote teams adopted more. Documenting everything. Not because you love writing things down for the sake of it. But because clear, accessible documentation is what makes async work. When decisions live in your head (or in some Slack Channel), people have to ask to catch up. Which means more meetings. More repeating. More “Can you remind me where that stands?” More/Better documentation means… → Everyone has the context they need Async doesn’t mean you lose visibility. It means you gain clarity—without the meeting. Because if your documentation does the talking, your team can get back to building.  ( 3 min )

Amazon EKS (Elastic Kubernetes Service) makes running Kubernetes on AWS easier, but keeping costs under control can be a challenge. As your workloads grow, so do the expenses, and without a clear strategy, it’s easy to end up with a sky-high cloud bill. According to the 2025 State of Cloud Costs by Datadog, over 80% of container spend goes to waste. Most teams over-provision CPU and memory to handle peak loads, but actual usage rarely matches these allocations. This leads to underutilized nodes, inflated infrastructure costs, and inefficient autoscaling. To optimize EKS costs effectively, you need to understand where your money is going and how to make the most of your resources. In this guide, we’ll break down the key areas of EKS cost management and share practical tips to help you reduc…  ( 10 min )

Key takeaways: Historical chart patterns and the Fibonacci Retracement metric hint at a Solana price rally to $300. Solana’s $7.5 billion in futures open interest and negative funding rates could be a sign that a powerful short squeeze is in the making. Solana (SOL) price tested the $180 resistance level on May 11, but it has since consolidated below this key threshold and appears unable to establish a sustained bullish position. However, the altcoin has maintained a positive signal by closing above the 50-week exponential moving average (EMA) for three consecutive weeks.

Key takeaways: 97% of ETH put options will expire worthless if ETH holds above $2,600. A bullish ETH price outcome could be limited by macroeconomic factors and trading strategies that cap Ether gains. On May 30, $2.4 billion in Ether (ETH) options will expire—an event that could support ETH’s attempt to break above the $2,700 mark for the first time in over three months. Despite the recent gains, Ether is down 21% in 2025, while the broader cryptocurrency market has seen a 5% increase. Ether bulls are motivated to keep ETH above $2,600 ahead of the monthly expiry.

The US Labor Department has officially rescinded guidance issued during the Biden administration that limited the inclusion of cryptocurrency in 401(k) retirement plans. On May 28, the Labor Department revoked a 2022 guidance that had urged fiduciaries to be “extremely cautious” when considering cryptocurrency for 401(k) retirement plans. The move could give asset managers more flexibility to include digital assets in retirement investment options. The government agency removed the guidance asserting that it represented a departure from the department’s “historically neutral, principled-based approach to fiduciary investment decisions.” “We’re rolling back this overreach and making it clear that investment decisions should be made by fiduciaries, not D.C. bureaucrats,” said US Secretary of…

Key takeaways: Bitcoin researcher Sminston With says BTC could gain 100% to 200%, with a cycle peak between $220,000 to $330,000. Bitcoin continues to exhibit strong cyclical volatility, contradicting the belief that its price swings are softening over time. Over $4 billion in BTC has been moved by long-term holders, warning of a price correction. Analysis from Bitcoin (BTC) researcher Sminston With implied that a BTC price peak is still 100% to 200% away from current prices. In a recent X post, With shared a Bitcoin price chart using a 365-day simple moving average (SMA) aligned with a power law model (R²=0.96). The model suggests Bitcoin’s price follows a predictable, non-random pattern over time, distinct from the exponential growth models often applied to stocks and equities. Bitc…

Bilal Bin Saqib, head of Pakistan’s crypto council, announced on May 28 that the country is moving to establish a strategic Bitcoin reserve. Speaking at the Bitcoin 2025 conference in Las Vegas, Nevada, Saqib said the government of Pakistan followed the United States’ lead in establishing a Bitcoin strategic reserve and is embracing pro-crypto regulatory policies. The government official told the audience: "Today is a very historic day. Today, I announce the Pakistani government is setting up its own government-led Bitcoin Strategic Reserve, and we want to thank the United States of America again because we were inspired by them." The announcement represents a significant departure from the government of Pakistan’s previous stance on cryptocurrencies, holding that crypto would never be legal in the country. Pakistan’s shift reflects the broader trend of nation-states adopting pro-crypto policies following the regulatory shift in Washington, DC under the President Donald Trump administration.

Background of Coinbase’s May 2025 breach Coinbase, America’s largest cryptocurrency exchange, received an unsolicited email from an unknown threat actor on May 11, 2025. They claimed to possess sensitive information about its customers and demanded a ransom of $20 million.  Before examining the breach, it is interesting to understand how it happened at a public company that spends millions monthly on cybersecurity. In February, blockchain investigator ZachXBT reported increased thefts involving Coinbase users. He blamed aggressive risk models and pointed out Coinbase’s failure to prevent $300 million in yearly losses from social engineering scams.  A table ZachXBT shared on X showed $65 million stolen from users between December 2024 and January 20…

Opinion by: Scott Buchanan, chief operating officer of Bitcoin Depot A new proposal to install Bitcoin ATMs in federal buildings highlights an important question: Can crypto truly go mainstream without a stronger physical presence? For years, the industry has focused on software and decentralization, but its reluctance to invest in real-world infrastructure is starting to show. Without physical access points, crypto risks becoming an exclusive, insiders-only system, rather than the open alternative it sets out to be. Everyone loves to talk about decentralization. There’s a good reason behind this. It defines the movement, shapes the technology, and supports the vision of a better financial system. While the industry focuses on code and algorithms, it lacks something basic. A decentralized …

Why are seniors being targeted in crypto scams? Scammers prey on seniors because they view them as financially secure, trusting and less familiar with rapidly evolving technology. Let’s understand why seniors are key targets. Perception of wealth: Many older adults have retirement savings or pensions, making them lucrative targets. Lower tech fluency: Navigating crypto wallets, private keys and blockchain concepts can be intimidating, something scammers exploit. Embarrassment prevents reporting: Victims often feel ashamed, making them less likely to report the crime. Crypto is irreversible: Once funds are sent via Bitcoin or another cryptocurrency, there’s no reversing the transaction. That’s a dream scenario for scammers. According to the Federa…

Key takeaways Lottery mining is cheap and fun, but don’t count on hitting a block. Solo ASIC mining gives you complete control, but it’s a long-odds game. Pool mining is the most practical way to earn steady payouts at home. Cloud mining saves you the hassle but usually isn’t worth the cost. Bitcoin is rapidly gaining legitimacy, and you couldn’t be blamed for wanting to peek behind the curtain to see how it’s made. Throughout 2024 and into 2025, you've seen a whirlwind of institutional investment from companies like Strategy, which continues to aggressively accumulate Bitcoin (BTC), and Metaplanet, Japan’s listed company that recently adopted BTC as a treasury reserve asset.  Moreover, on the regulatory front, the return of a US President Donald Trump administration signals a friendlier …

Top Bitcoin (BTC) bulls in 2025 have updated their price forecasts, and they range from a relatively cautious $130,000 to seven-figure moonshots. Familiar doubters like gold bug Peter Schiff and economist Nouriel Roubini continue to predict a catastrophic ending for the world’s largest cryptocurrency. Meanwhile, Bitcoin spent the year with record-breaking rallies behind renewed institutional uptake. It set a new all-time high of $111,970 on May 22 and has been trading near that level since, teasing investors with the possibility of a new ceiling.

Non-fungible tokens (NFTs) caught an uptick in monthly sales in May after months of consistent decline throughout 2025.  Data from CryptoSlam shows that May’s NFT sales climbed to $430 million, up from $373 million in April, a 15% increase. It marks the first monthly sales increase since the start of the year, suggesting renewed interest in digital collectibles.  This follows a five-month decline in sales since volume peaked at over $900 million in December 2024. May also had the highest number of transactions in 2025, reaching 5.5 million, according to CryptoSlam.  The sales uptick could also be attributed to the divergence between unique NFT buyers and unique NFT sellers. NFT buyers continued to increase in May, while sellers declined.  Chart compiled by Cointelegraph to demonstrate Cryp…

Key points: Bitcoin price is stuck in a range, with overhead resistance at $110,000 continuing to obstruct a rally to new all-time highs. Traders are in a wait-and-see mood due to uncertainty surrounding macroeconomic events. Bitcoin’s (BTC) bull run has stalled, with the price consolidating within a roughly $3,500 range since May 23.

Swiss crypto bank Amina Bank, formerly Seba Bank, reported record financial results for 2024, with revenue climbing 69% year-over-year to $40.4 million. The bank also saw its assets under management (AUM) rise by 136% to $4.2 billion, driven by institutional demand and strategic expansion, according to a May 28 news release. The Zurich-based bank credited the growth to its multi-jurisdictional footprint, 24/7 trading capabilities and a lending book that has maintained zero defaults over five years. “I’m incredibly proud of our team’s tenacity and focus, which led to quarterly profitability in Q4 2024, a pivotal milestone that confirms the value of our approach,” CEO Franz Bergmueller said.

Telegram is expected to raise at least $1.5 billion in a bond issue on May 28, with support from existing backers like BlackRock and Abu Dhabi’s investment firm Mubadala, The Wall Street Journal reported.

Ripple, the blockchain company behind XRP, argued that fungible cryptocurrencies are not securities when transferred in secondary transactions in a recent letter sent to the US Securities and Exchange Commission (SEC). In its May 27 letter, Ripple cited US attorney and crypto law thought leader Lewis Cohen to support its claim. In his widely cited 2022 paper, “The Ineluctable Modality of Securities Law: Why Fungible Crypto Assets Are Not Securities,” he wrote: “[T]here is no current basis in the law relating to ‘investment contracts’ to classify most fungible crypto assets as ‘securities’ when transferred in secondary transactions.” In his paper, Cohen explained that in secondary transactions, an investment contract transaction is generally not present. He further claimed that fungible cry…

Sui-based decentralized exchange Cetus may be one step closer to recovering funds lost in a recent exploit, pending the outcome of a community governance vote scheduled to end June 3. Cetus was exploited for over $220 million worth of digital assets on May 22. Shortly after the incident, Cetus managed to freeze $162 million of the funds. In a May 27 post on X, Sui said Cetus had requested a community vote to approve the recovery of the frozen funds. “If the community vote is approved, the funds will be recovered from the attacker and held in a multisig trust account until they can be returned to accounts that had positions in Cetus,” the post said. The vote is part of a broader recovery plan that includes using Cetus’s treasury and securing an emergency loan from the Sui Foundation. Sou…

White House AI and crypto czar David Sacks says the US could buy more Bitcoin if the government can fund the purchase in a “budget-neutral” way without a tax or adding to the growing national debt. Sacks told Gemini co-founders Cameron and Tyler Winklevoss during a May 27 fireside chat at the Bitcoin 2025 conference that while he “can’t promise anything,” a pathway does exist for the government to buy more Bitcoin (BTC). However, it would require convincing Commerce Secretary Howard Lutnick or Treasury Secretary Scott Besson to OK the buy and fund it “without a new tax or adding to the debt,” Sacks said, adding that “maybe by finding the money from some other program that’s not using it — then we could potentially acquire more Bitcoin.” David Sacks said the US could buy more Bitcoin, but h…

The International Monetary Fund said it has reached an agreement with El Salvador to pay the country $120 million following an initial review of its $1.4 billion loan agreement struck last year. The IMF said on May 27 that as part of the deal, El Salvador will need to fulfill its prior obligations around limiting further government involvement in Bitcoin (BTC), and it will have to cease its involvement in the Chivo wallet by the end of July. “On Bitcoin, efforts will continue to ensure that the total amount of Bitcoin held across all government-owned wallets remains unchanged,” the global lender said. The planned payout, subject to IMF executive board approval, is part of a larger $1.4 billion, 40-month loan deal struck in December, which saw El Salvador agree to confine its Bitcoin ambiti…

Outgoing US Commodity Futures Trading Commission commissioner Christy Goldsmith Romero says the exodus of the agency’s top brass is “not a great situation” for crypto regulations. The CFTC could be headed by just one commissioner once the other four depart later this year, which Goldsmith Romero said in a May 27 interview at the Brookings Institution will make creating regulations harder because it leaves a less diverse pool of opinions.  “I think it’s not a great situation if you have one person who’s determining what the rules should be; you lose the benefit of this back-and-forth, this push-and-pull as to what’s the right thing to do,” she said. “I’ve always wanted to hear from my fellow commissioners about what makes sense to them, and there are many things that they’ve convinced me of…

Bitcoin’s recent all-time high of $111,970 has sparked optimism among crypto market participants, but whether that carries through into the third quarter of this year remains uncertain, analysts say. “The coming weeks will likely determine whether Bitcoinʼs latest breakout was a local high or the prelude to a more aggressive leg higher in Q3,” Bitfinex analysts said in a May 28 markets note. Consolidation or mild retracement may “be healthy” Bitcoin (BTC) reached new all-time highs of $111,970 on May 22, however, Bitfinex analysts say a continued price increase alone won’t necessarily confirm the uptrend heading into the next quarter.  “A period of consolidation or mild retracement would not only be healthy but also provide a more sustainable foundation for the next leg higher,” the analys…

Real-world assets linking up with non-fungible tokens (NFTs) is one of a few key catalysts that could reignite the waning NFT lending sector, which is suffering from a collapse in volumes and user activity, says blockchain analytics platform DappRadar. Volumes in the NFT lending market, which allows NFT holders to take out a loan against their token, have dropped 97% from a peak of around $1 billion in January 2024 to $50 million in May, DappRadar analyst Sara Gherghelas said in a May 27 report. Gherghelas said for NFT lending to “move beyond survival mode,” it needs “new catalysts” to reignite the sector, such as real-world asset NFTs, like tokenized real estate or yield-bearing assets that could unlock more stable, trusted collateral sources. “So far, 2025 has not delivered a compelling …
